TCPSER turns a PC serial port into an emulated Hayes compatible
modem that uses TCP/IP for incoming and outgoing connections.
It can be used to allow older applications and systems designed
for modem use to operate on the Internet. TCPSER supports all
standard Hayes commands, and understands extended and vendor
proprietary commands (though it does not implement many of
them). TCPSER can be used for both inbound and outbound
connections.
