Hi,
I just downloaded the driver for my PCTel modem. I compiled it under a
2.4.7 and a 2.4.10 kernel. Both times I get unresolved symbols, whne I run
a depmod -a. When I insert the modules pctel and ptserial I get:
Sep 28 16:42:26 gweber kernel: AC97 modem device found: devnum = 80000200,
devid
= 8086/7196
Sep 28 16:42:26 gweber kernel: irq = 5, iobase_0 = 1000, iobase_1 = 1C00
Sep 28 16:42:26 gweber kernel: PCTel driver version 5.05c-pctel (MR)
(2001-08-08
) with MANY_PORTS SHARE_IRQ SERIAL_PCI enabled.
Sep 28 16:42:26 gweber kernel: ttyS15 at 0x1000 (irq = 5) is a PCTel
Sep 28 16:42:26 gweber kernel: PCI: Found IRQ 5 for device 00:00.2
Sep 28 16:42:26 gweber kernel: PCI: Sharing IRQ 5 with 00:06.0
Sep 28 16:42:26 gweber kernel: PCI: Sharing IRQ 5 with 00:0c.1
Sep 28 16:43:33 gweber kernel: PCTel initialization. Country code is 1.
Which seems fine to me. But when I try to access ttyS15 with minicom the
program crashes with a segmentation fault:

Was anybody successfull get this driver working? I'm also not sure, which
chipset to use in the makefiles. Now I use the I810 which was the only one
where I got an interrupt message in /var/log/messages.
Thanks
Gernot
