# probemodem(8)

check modem and report the result of certain commands

## NAME

probemodem - check modem and report the result of certain commands

## SYNOPSIS

**/usr/sbin/probemodem** *\[-f\] \[-c AT\_COMMAND\] \[-s SPEED\] \[ttyname\]*

## DESCRIPTION

The **probemodem** script checks a modem attached to a serial line and reports the results of certain commands.

The *ttyname* argument is the name of the tty port that the modem is attached to.

This manual page was written for the Debian GNU/Linux distribution (but may be used by others), because the original program does not have a manual page.

## OPTIONS

- **-f**

  Do not use the command fuser in order to check if other processes are using the tty *ttyname* and kill them

- **-c** *AT\_COMMAND*

  Specify a string to be sent to the modem instead of "AT+FCLASS=?"

- **-s** *speed*

  Set the speed to use for the *ttyname* port
