Usually com 1 shares the same IRQ with com 3 (and 2 w 4). This is set up in the Bios, and the kernel gets the irqs from what the bios tells it, I think. But there are some HOWTOS docs on the suse CDs you can read; for example: | Serial HOWTO | David S.Lawyer dave@lafn.org original by Greg Hankins | v2.16 March 2002 | | This document describes serial port features other than those which | should be covered by Modem-HOWTO, PPP-HOWTO, Serial-Programming-HOWTO, | or Text-Terminal-HOWTO. It does not cover the Universal Serial Bus | (see the kernel documentation for USB). It lists info on multiport | serial cards. It contains technical info about the serial port itself | in more detail than found in the above HOWTOs and should be best for | troubleshooting when the problem is the serial port itself. If you | are dealing with a Modem, PPP (used for Internet access on a phone | line), or a Text-Terminal, those HOWTOs should be consulted first. -- Cheers, Carlos Robinson
