USR hard modem not working with Mandrake8

[danielshoes]

I've just installed Mandrake 8. It is working fine, but my modem doesn't work. It is a 3Com/USR OEM hardware modem PCI with voice (model 2976). Mandrake 8 had detected it as another model.
So, when I try to connect, a box pops up telling that the modem is not responding or is is already in use.

How do I configure this modem?

Come on...

 

[DaHitman]

This modem uses a non-standard IRQ/address and requres special configuration since the mfgr didnt see fit to use a standard IRQ... some PCI modems do that.

There is info here:
http://www.linuxdoc.org/HOWTO/Modem-HOWTO.html

Thank you!
Actually, I've just visited that page before posting, but as that page has thousands links to browse, I thought easier to ask to the Anandtechers...

I will try to search this info on that page, but I would like to share experiences with others that had problems with modems configurations (not winmodems) under Linux.

Yes, having someone do the work for you is always easier than trying to do it yourself....

n0cmonkey, don't say it... cause I am seaching this info for hours and hours on the net! And I've searched that site suggested for DaHitman (in fact, a very good site!), but unfortunately didn't find anything specific to make this modem work.

Fortunately, I found this page, describing the procedure for this exact modem to work under Linux!

DaHitman, I guess you are correct when says that this modem uses non-standard IRQ/address. In WinMe it is assigned to COM5 (it ONLY WORKS if assigned to COM5). In Linux it is alocated to ttyS4! This device does not exist in kpp configuration options and I couldn't change it. Interestingly, under Win2k it is assigned to COM3.

Following the step by step described on that page I've found, I can make the modem work and the message &quot;modem busy&quot; no more appear. But I must run the commands again at every boot to make the modem work.
The commands are:

setserial /dev/ttyS4 irq 11 port 0xc000 ^fourport ^auto_irq skip_test autoconfig spd_vhi

ln -sf ttyS4 modem (under the /dev directory)

I want to make it permanent. Is there a way to create an executable file (like a .bat file under DOS/WIN) to run these commands at every boot under Mandrake 8?

Yes there is. I am not too familiar with the SVR4 style of startup configuration so I will give you a rough guess. write a simple shell script (I will put a possible script at the end) name is something like S05ttystuff. Put it in /etc/initd/rc.5 (might be 4 or 3 it all depends on which init the system starts up to and Im not sure if I can correctly describe these to you...).

I recommend reading up on how mandrake starts up to make sure this will work and if I have the info correct and which init level you start up at.

#!/bin/sh
setserial /dev/ttyS4 irq 11 port 0xc000 ^fourport ^auto_irq skip_test autoconfig spd_vhi
ln -sf /dev/ttyS4 /devmodem
