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 com-
mands, 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.
-N Filename to send when no answer.
-B Filename to send when modem(s) busy.
-T Filename to send upon inactivity timeout.
-i Modem init string (defaults to `', leave off `at' prefix when specifying).
-D Direct connection (follow with hostname:port for caller, : for receiver).
