Virtual Serial Port Driver
SMBCreates virtual COM ports and redirects serial data over network or Bluetooth connections.
Persistent COM port mapping keeps the same port numbers stable across restarts for serial-dependent applications.
Virtual Serial Port Driver is built around a Windows driver that enumerates virtual COM ports and connects them to network endpoints using its own client and server mapping modes. It targets industrial workflows that depend on serial device enumeration and expects host software to treat the remote side as a local COM port. Port mapping configuration supports reconnect handling and session stability so applications keep their expected COM handles. The tool is most useful when a serial-over-IP link must preserve serial port behavior rather than using a generic TCP protocol.
A tradeoff appears in operational complexity because network redirection rules and serial settings must be coordinated across both ends. A common usage situation is routing multiple field devices through a controlled gateway host where local automation software opens fixed COM ports and the driver forwards those sessions to the right TCP endpoints. Another fit scenario is serial device server chaining where a management PC initiates connections to reach hardware behind constrained network segments.
- +Persistent virtual COM identities reduce host app reconfiguration
- +Network redirection supports TCP-based serial-over-IP sessions
- +Serial signaling changes can be propagated through the redirector
- +Windows driver deployment supports stable long-running routing
- –Mapping rules require careful coordination across endpoints
- –Deep debugging of network sessions needs extra operational steps
- –High connection counts can increase Windows service overhead
- –Throughput tuning depends on consistent serial and socket parameters

Best for: Fits when host software requires stable COM ports for serial-over-IP access behind gateways.
Advanced Virtual COM Port
SMBVirtual serial port creation and redirection software for Windows environments.
Server-side COM mapping that keeps serial-to-network behavior hidden from client serial applications.
Advanced Virtual COM Port is designed for environments that need COM port enumeration compatibility for existing serial tooling. It runs as a Windows service, so COM port mapping can persist while applications open ports using normal Windows serial APIs. The key capability is server-side mapping of local COM endpoints to remote TCP connections, which keeps third-party apps unaware of the network hop.
A practical tradeoff is that TCP-based redirection requires careful attention to target reachability and session lifecycle so disconnects do not leave applications hung. It fits best for labs, remote device consoles, and industrial automation integration where operators rely on terminal tools, custom field utilities, or serial middleware that expects a COM device.
- +Creates standard COM ports for serial-only Windows applications
- +Supports TCP-based redirection so remote devices require no app changes
- +Runs as a Windows service for persistent port mapping
- +Maintains mapping stability for serial tool workflows

It supports serial-to-IP tunneling patterns where the Windows machine terminates the COM port and forwards serial traffic over TCP to a remote serial device server. The tool includes reconnect handling so COM sessions can recover when the remote endpoint drops.
A tradeoff is that throughput depends on how the Windows host and TCP path are tuned, so it may require careful serial framing and flow-control settings for high-rate links. It fits best when a control room workstation needs to access multiple industrial endpoints through stable COM port enumeration during remote console access.
- +Preserves serial line settings and modem control signals through redirection
- +Reconnect handling reduces manual restarts after network endpoint drops
- +Windows service deployment supports ongoing serial workflows
- +Uses COM port mapping that remains stable after reconfiguration

How to Choose the Right com port redirector software
A com port redirector software stack makes Windows serial applications talk to a remote or alternate endpoint by presenting a virtual COM port and redirecting the underlying serial session over a network transport. This roundup covers Virtual Serial Port Driver, Advanced Virtual COM Port, Serial Port Redirector, Serial to Ethernet Connector, HW VSP3, Serial/IP, com0com, Tibbo Device Server Toolkit, Digi RealPort, and Moxa NPort Driver.
The practical differences show up in persistent port mapping behavior, reconnect handling after TCP interruptions, and whether routing stays server-side while client applications keep their standard COM enumeration. Several tools also differ in how much operational coordination they require across endpoints, especially when many virtual endpoints and policies must stay consistent.
What com port redirector software does: virtual COM mapping and redirecting serial sessions
Com port redirector software creates or emulates Windows COM ports and then redirects each port’s serial I/O to a different target by applying server-side COM mapping and session controls. Virtual Serial Port Driver, for example, keeps the same virtual COM port numbers stable across restarts using persistent COM port mapping, and it uses reconnect behavior to keep COM usage stable after TCP interruptions.
Advanced Virtual COM Port focuses on hiding the network behavior from the serial-only Windows apps by keeping the server-side COM mapping behavior consistent while the redirect runs over TCP. Across the category, the core value comes from stable virtual COM identities, preserved serial line settings and modem control handling in the redirect path, and operational behaviors that determine how reliably virtual COM access recovers after disconnects.
What to evaluate in com port redirector software
Virtual COM port persistence determines whether legacy serial applications keep working after services restart, especially when host software hard-codes COM numbers. Virtual Serial Port Driver, for example, keeps the same port numbers stable across restarts using persistent COM port mapping, which reduces application reconfiguration.
Reconnect handling and session recovery decide whether network interruptions force manual relaunches. Serial Port Redirector adds per-port session persistence with reconnect behavior that keeps COM usage stable after TCP interruptions, while Advanced Virtual COM Port requires network session tuning to avoid stalls on disconnects.
Persistent COM identity across restarts
Virtual Serial Port Driver and Serial to Ethernet Connector both focus on stable virtual COM endpoint behavior so unchanged Windows serial APIs keep targeting the same COM names after restarts.
Reconnect and disconnect recovery behavior
Serial Port Redirector and Advanced Virtual COM Port differ in how they handle disconnect recovery, with Serial Port Redirector emphasizing reconnect behavior and Advanced Virtual COM Port requiring network session tuning to avoid stalls.
Server-side routing that hides network behavior from serial apps
Advanced Virtual COM Port and HW VSP3 both present standard COM ports to serial-only Windows applications while keeping the mapping and routing behavior on the server side.
Signal and modem-control preservation
Serial Port Redirector and Digi RealPort each emphasize control-line behavior, with Serial Port Redirector preserving serial line settings and modem control signals through redirection and Digi RealPort passing through DTR, DSR, RTS, and CTS signaling.
Throughput and latency sensitivity under TCP transport
Serial Port Redirector and Serial to Ethernet Connector both call out TCP tuning as a practical factor, because throughput and latency hinge on TCP settings aligned with serial choices in both products.
Multipoint versus point-to-point operational fit
Virtual Serial Port Driver and Serial/IP diverge on multipoint complexity, because Virtual Serial Port Driver warns that multipoint coordination requires careful rule design while Serial/IP flags multipoint fan-out as operational complexity versus point-to-point tunneling.
How to choose a com port redirector by routing control, stability, and operations
Selection should start with whether the host application expects stable virtual COM port numbers, because persistent mapping is the difference between a routing change and an application change. Virtual Serial Port Driver and Advanced Virtual COM Port both keep client apps on standard COM enumeration, but they differ in how the network behavior is handled when sessions drop.
Next decide whether routing must be server-managed for unattended Windows service deployment, because several tools emphasize headless operation while others depend on more disciplined orchestration. HW VSP3 and Serial to Ethernet Connector lean toward Windows service deployment for long-lived routing, while Tibbo Device Server Toolkit shifts complexity into buildable device-server extension hooks.
Match COM stability requirements to persistent mapping behavior
If host software depends on unchanged COM numbers after restarts, prioritize Virtual Serial Port Driver persistent COM port mapping and Serial to Ethernet Connector persistent COM endpoint behavior. If stable COM names are needed but the routing design can tolerate more operational work, Advanced Virtual COM Port’s server-side mapping can still satisfy remote access with unchanged Windows serial apps.
Plan for disconnect recovery based on each tool’s reconnect assumptions
If TCP interruptions should not trigger frequent manual restarts, use Serial Port Redirector because it includes per-port session persistence and reconnect handling. If the environment can provide disciplined network session tuning, Advanced Virtual COM Port can keep serial apps unchanged while the redirect runs over TCP.
Pick the routing posture for your deployment model
For server-managed routing that keeps serial-only applications pointed at standard COM ports, choose Advanced Virtual COM Port or HW VSP3. For service-based virtual COM access with persistent per-port session configuration in industrial Windows systems, Serial/IP fits a Windows service style deployment model.
Confirm modem-control and serial line behavior expectations
For environments that must preserve serial line settings and modem control signals, choose Serial Port Redirector. For deployments that rely on explicit DTR, DSR, RTS, and CTS passthrough across the redirect path, Digi RealPort is built around control-line passthrough tied to reconnect behavior.
Select based on throughput and latency tolerance under TCP transport
If the serial workload is sensitive to TCP tuning, compare Serial Port Redirector and Serial to Ethernet Connector because both highlight that throughput and latency depend on TCP settings aligned with serial and flow-control choices. If workload is mostly local serial endpoint testing without network tunneling, com0com is a fit because it creates persistent virtual COM pairs on one machine.
Decide whether multipoint access is a core requirement or a design constraint
If multipoint serial access is required, treat coordination cost as a design variable by comparing Virtual Serial Port Driver warnings about multipoint coordination with Serial/IP multipoint operational complexity. If only local process-to-process serial endpoint redirection is needed, com0com avoids network fan-out entirely.
Who com port redirector software fits
Com port redirector software fits when Windows serial applications must keep their COM enumeration model while routing serial I/O over a network transport. It also fits when industrial Windows systems need stable virtual endpoints for long-running routing with service-based deployment.
Tool differences matter most for persistence semantics, reconnect behavior, and how control-line handling is treated during redirection, because those determine whether field operations require manual recovery steps.
Integrators supporting remote serial access for legacy Windows apps
Advanced Virtual COM Port and HW VSP3 keep serial applications on standard COM enumeration while maintaining server-side COM mapping for remote access.
Operations teams that need COM numbers to remain stable after restarts
Virtual Serial Port Driver and Serial to Ethernet Connector focus on persistent virtual COM endpoint behavior so serial-dependent applications do not need COM remapping after service cycles.
Industrial environments where disconnect recovery must be automatic
Serial Port Redirector and Serial/IP target dependable virtual COM operation under Windows service deployment, but Serial Port Redirector emphasizes reconnect handling tied to per-port session persistence.
Projects that require explicit modem-control passthrough
Digi RealPort is built for DTR, DSR, RTS, and CTS signaling passthrough with COM persistence tied to reconnect behavior, while Serial Port Redirector preserves modem control signals through redirection.
Teams building repeatable serial redirection policies across many endpoints
Tibbo Device Server Toolkit provides device-server extension hooks that support custom client-to-serial redirection policy logic beyond static COM mappings, at the cost of more engineering.
Common pitfalls in com port redirector software deployments
A common mistake is treating virtual COM mapping as purely cosmetic, then discovering host software breaks after service restart because COM numbers changed. Persistent COM mapping behavior is a category requirement in many deployments, and Virtual Serial Port Driver specifically keeps virtual COM port numbers stable across restarts.
Another frequent pitfall is ignoring disconnect and session recovery behavior until the first real network interruption. Serial Port Redirector includes reconnect handling and per-port session persistence, while Advanced Virtual COM Port depends on network session tuning to avoid stalls on disconnects.
Selecting a tool without persistent COM mapping and then hard-coding COM numbers in host applications
Use Virtual Serial Port Driver or Serial to Ethernet Connector when host apps require stable COM names across restarts, because both tools are built around persistent COM endpoint behavior.
Assuming disconnect recovery works the same way under TCP transport
Use Serial Port Redirector if network drops must not force repeated manual restarts, and validate how Advanced Virtual COM Port behaves when network sessions stall on disconnects.
Underestimating the effect of control-line handling on application behavior
If DTR, DSR, RTS, and CTS must match local expectations, Digi RealPort is designed for control-line passthrough, and Serial Port Redirector also preserves modem control signals through redirection.
Treating multipoint access as a free upgrade from point-to-point routing
Plan coordination effort for multipoint design by comparing Virtual Serial Port Driver multipoint coordination needs with Serial/IP operational complexity in multipoint fan-out.
Choosing a local-only emulator for a network routing requirement
Use com0com only for local process-to-process virtual COM port pair testing because it does not include IP transport or network serial tunneling unless bridged externally.
