tcpser

Hayes Smartmodem emulator over TCP/IP

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.
