NAME

       tcpser - emulate a Hayes compatible modem

SYNOPSIS

       tcpser -d dev -s speed [-l log_level -t tracing_options] ...
       tcpser -v port [-l log_level -t tracing_options] ...

DESCRIPTION

       This manual page documents briefly the tcpser command.

       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.

       if not set again):

       -d     Serial device (e.g. /dev/ttyS0).  Cannot be used with -v

       -v     TCP port for VICE RS232 (e.g. 25232). Cannot be used with -d

       -s     Serial port speed (defaults to 38400).

       -S     Speed modem will report (defaults to -s value).
