us robotics sportster (pci) modem problems on mandrake 9.2 and 10

Hello !

I am having problems getting my modem work with mandrake. It's an internal pci hardware modem. Mandrake doesn't recognize it and I use setserial to assign I/O adress to the serial driver:

# lspci -v

here I find out what IRQ and I/O adress is set in the modem; ports 9000, IRQ 11

then i give a setserial command:

# setserial /dev/ttyS4 port 9000 irq 11 uart 16550A

and then link /dev/modem to /dev/ttyS4

And i believe that should be sufficient. After that the modem was working under debian, redhat and mandrake 9.0 but it's not working with mandrake 9.2 or 10.0. I echo an ATDT 039840 to /dev/ttyS4, and nothing happens, and kppp says "modem is busy".

Any suggestions ?

One more thing: irq 11 is already assigned to the graphics adapter and I'm unable to change it with "setpci". Does that matter ? I had a similar situation before and when I dialed in it was obvious that graphics performance decreased; windows that were being dragged around the screen were leaving trails !

And another one: Even when that modem is working there are problems with it - the first dialin after a reboot always results in error 16 "modem hangup". My friend told me that he was experiencing the same and he fiixed it, but he doesn't remember how

No need to bother with the first problem. I forgot that I dont have write permissions for /dev/ttys/4. I set it and it works. I'm using it now
