I'm running the Yggdrasil LGX F93 kernel, and any attempt to use
/dev/cua1 (including to run setserial) results in "Device or resource
busy". (Ditto /dev/ttyS1, unsurprisingly.) I have a mouse on com1
(/dev/cua0), and I can use kermit to connect to the mouse and see
gibberish at 1200baud when I move it. I have an external modem on
I checked the serial-FAQ, but didn't get far:
-- there are no getty processes on the serial line, just on tty[1-4]
(my four virtual consoles). I checked both inittab and `ps aux`
-- the FAQ suggests remaking the kernel, but I tried that and the
kernel sources as distributed won't build.
I have an SMC Ethernet card plugged into the system that I have never
used. Could it be causing the problem? If so, is there a cure other
than ripping it out?
Can anyone suggest any other cures? My linux box is pretty useless if
I can't talk to the world...
