- Okay, here's the problem. My system is a Micron P100/PCI with an internal
- PnP 14400 Prometheus modem. General opinion in Usenet is that this modem
- isn't worth much; so be it. When I boot in Win95, the modem seems to have
- been assigned COM2 and IRQs 9 and 5. I don't know why one device requires
- two IRQs, but again, so be it. I am able to use the modem pretty much
- normally under Win95.
-
- When I boot to Linux 1.2.13 and try to run Kermit (the prompt says
- "C-Kermit 5A(190), 4 Oct 94, for Linux"), I get the message
-
- /dev/modem is not a terminal device
-
- (Note /dev/modem is symlinked to /dev/cua1 on my system). So I
- tried running (as root)
-
- cd /dev
- MAKEDEV -v -d ttyS1
- MAKEDEV -v ttyS1
- setserial /dev/cua1 uart 16550A irq 9
-
- Now Kermit gives me the message:
-
- Sorry, can't open connection: /dev/modem: No such device
-
- Changing the irq to 5, or to 3, doesn't change anything. Nor does
- setting the UART to 16450.
- However, plugging my klunky old 2400b external modem into the COM1
- serial port and telling Kermit to use /dev/cua0 works just fine.
- This also works with minicom and with seyon.
- I noticed the following in the man pages to MAKEDEV:
-
- Note that programs giving the error ``ENOENT: No such file
- or directory'' normally means that the device file is
- missing, whereas ``ENODEV: No such device'' normally means
- the kernel does not have the driver configured or loaded.
-
- Can this be true? Does the kernel really need a different driver for
- an internal PnP modem? If so, perhaps someone could explain how to
- obtain/configure/load such a driver, or at least point me to where I
- could read about it.
-
- Thanks,
- Baffled George
