I just went through this with a Motorola ModemSURFR(tm) 56K I got cheap at the Dell factory outlet here in Austin. Windows 3.11 recognized it as COM4 with IRQ 5 and port 0x2e8. After much playing with FreeBSD 2.2.6 and PnP, I discovered that if I set the port and IRQ exactly the same way Windows set it, everything worked fine! I think the 2.2.6 PnP stuff or the card itself were originally picking port 0x3e8 and messing up. Another thing I did was to add the card to the siopnp_ids[] array in /usr/src/sys/i386/isa/sio.c. This made the system automagically recognize the card as a modem and set it up as sio1. If you do this sort of trick, you MUST still configure at least one of your normal serial ports (sounds like the original poster had another modem that was hardwired to a specific IRQ, so that will work), otherwise config will think you have no serial ports whatsoever, and the sio code won't be included at all. The FAQs and handbook are a little sparse on PnP, unfortunately. -Dave To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
