# iprofd(8)

Modem-register daemon

## NAME

iprofd - Modem-register daemon

## SYNOPSIS

**iprofd** *registerfile*

## DESCRIPTION

**iprofd** is used to make the modem-register settings of the isdn-ttys AT-emulator permanent and restore them during boot-time. It is usually started from within a rc-script and puts itself into background. If *registerfile* already exists at startup, all modem-registers are restored from it's contents. After that, **iprofd** waits for getting a signal from the isdn-subsystem. Every time, a 'AT&W0' command is given at an isdn-tty the isdn-subsystem sends a SIGIO and **iprofd** reads the current settings of the modem-registers and stores them into *registerfile*.
