next in thread | raw e-mail | index | archive | help
I apologize for the length of this e-mail, but I wanted to include all the
information I had on my problem. I am unsuccessfully trying to talk to a PCI
V.90 modem which I assume is a PnP modem. I am currently running a custom
kernel 3.2-Release which has the isa0, pnp0, and pci0 controllers. I'll
append the config file to this e-mail.
The modem is an OEM 3com model 3CP2977 of which I can find absolutely no
information. The motherboard is an ASUS P3B-F. The other peripherals in the
system are:
1 IDE Hard Drive
1 IDE CD-ROM driver
1 Floppy drive
1 AGP Video card
1 ISA PnP Sound card
I have tried using the PPP command in term mode to talk to the modem with
absolutely no success. I have set the device to each of the cuaa<X> values.
In fact, the system seems to find almost no evidence of the modem's
existence. Here is the output from running pnpinfo:

I thought perhaps the "100812b9: 16550 serial controller" might have been

don't want to.
