ISA Modem support for Linux :D

[Andrew Cz]

Last night I couldn't find a working download site for red hat so i managed to dig out a copy Corel Linux SE i had at the bottom of my drawer. Well the old 60mhz machine machine didn't like it, so i thought i'd go and install it on my main PC alongside windows. Installed smoother than windows but!

I cant get my modem to work. It simply isn't automatically detected and is not listed on the manual configuration. Can someone tell me where i can find drivers for a Rockwell 56kflex/V90 ISA PnP Modem? And posably tell me how to add these?

And Cragstar lol we have the same problem, hopefully you can help me at college!

And help greatly appreciated! Convince to get rid of windows!

Andy, have a look at my thread, there is a brilliant site fo r finding drivers for your modem.

[Andrew Cz]

Already have! cant find one for my hardware chipset.

I know this is probably obvious, but have you checked to see if the modem's PNP feature can be turned off and manually set the com/IRQ? Then use either the modem setup feature of the hardware manager or look in the book and check which file to manually link to dev/modem. Also, if you do set it manually, in the BIOS of the MACHINE turn off the PNP for the IRQ you end up using (set it to ISA/LEGACY if available).
To be on the safe side I bought a standard ISA Modem, that has its own controller, to be used in LINUX. ALSO, maybe you can find better info at the site below. GOOD-LUCK!

Depending on what kernel this is and how Corel distros play with IRQ's in general...

I had the same problem with my Supra under pretty much every Red Hat version I used, three total. The OS was assuming com1/irq4, com2/irq3, and com3/irq4. In PnP mode the Supra wants com3/irq5, so it didn't work.

If that's the case you could either jumper the modem to an IRQ that the OS will recognize, or change the default IRQ for the com port that it's installed on. I never tried it but I don't see why adding a setserial command with the IRQ you want at the end of your boot sequence (/etc/rc.d/rc.local) wouldn't work.

It'd look something like...

setserial /dev/ttys0 IRQ 5

Yeah the first thing i thought was to change the jumpers, however I dont have any litriture about the modem, and only settings on the modem are for plug and play. Well i'll see what i can dig up, i really would like to get linux up to scratch because i think if it was i would use it more than windows.

Whatever Windows shows the com port and IRQ as is what the BIOS sees it as. Compare Windows com/IRQ settings to your Linux IRQ settings.

setserial by itself will show you the IRQ and UART settings for a com port.

setserial /dev/ttys2

...will give you IRQ and UART info for that port, for instance. If the two don't match (Linux and Windows), you need to change one or the other, either modem or IRQ for that device.
