Appendix E. Inbound Connections
Overview
As typically used for outbound connections through a serial device server, the application
software uses the Serial/IP Redirector's client functions to communicate with the networked
serial device:

The Serial/IP Redirector can also be configured to accept inbound connections that are
initiated by a serial device server that supports client functions. This allows the application
computer to wait for a networked serial device to connect instead of polling it:

Alternatively, the connection may be initiated by an application on another computer (#2) that
is also running the Serial/IP Redirector. This allows the applications to communicate with
COM ports but use the network instead of a serial cable:
