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.
