TCPSER(1)                   General Commands Manual                  TCPSER(1)



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.


OPTIONS
       A summary of options is included below.

       -h     Show summary of options.

       -p     Port to listen on (defaults to 6400).

       -t     Trace flags: (can be combined)
                 s      modem input
                 S      modem output
                 i      IP input
                 I      IP output

       -l     Log level: 0 (NONE), 1 (FATAL) - 7 (DEBUG_X) (defaults to 0).

       -L     Log file (defaults to stderr).

       The following can be repeated for each modem desired (-s, -S, and -i
       will apply to any subsequent device 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).

       -I     Invert DCD pin.

       -n     Add phone entry (number=replacement).

       -a     Filename to send to local side upon answer.

       -A     Filename to send to remote side upon answer.

       -c     Filename to send to local side upon connect.

       -C     Filename to send to remote side upon connect.
