PnP does not respond to cu
Here's what's happening:
# cu --speed 115200 --line /dev/ttyS1
cu: open (/dev/ttyS1): Permission denied
cu: /dev/ttyS1: Line in use
# dmesg | grep tty
tty01 at 0x02f8 (irg = 3) is a 16450
# ls -l /dev/tty01
ls: /dev/tty01: No such file or directory
Questions:
1. Why does /dev/tty01 appear in dmesg?
2. Why does cu claim /dev/ttyS1 is tied up?
... has permission problems?
3. Do I need any special modules loaded into
my kernel? Eg, like a PnP module?
Regards,
-c
