i have problem in modem configuration on slackware 2.6.21.5-smp. i configured a hylafax server. so i need the modem to assign the serial port. how is the process to setup i don't know. i refered my site and i m trying very much. when i run the command lspci -v the modem is showing.

this is the o/p of the lspci -v
01:00.0 Communication controller: U.S. Robotics USR5660A (USR265660A, USR5660A-BP) 56K PCI Faxmodem (rev 01)

i m just putting the modem into serial port and not connected in any telephone connection and fax machine.

plz help me how to assign the modem to serial port. How to configure test the modem is work not.
i m waiting for ur valuable replies.

I have not tinkered with modems in a few years. However, I recall some files in Slackware that are important:

1. /etc/serial.conf
2. /etc/rc.d/rc.serial

The latter file needs to be executable (chmod +x). The first file might need some manual editing to properly assign ports.

Although not applicable to you, for some people using older ISA hardware, a third file that is important is /etc/isapnp.conf. The file does not exist in a stock Slackware and must be created using the isapnp tools.

You want to use the setserial command; this http://tldp.org/HOWTO/Serial-HOWTO-12.html might be interesting reading for you. Here's an old thread with an example:
http://www.linuxquestions.org/questi...serial-178924/

This is what I use (for example)

setserial /dev/ttyS2 uart 16550A port 0x9000 irq 16
