unable to see my serial port
Hello,
i have a dell server
that i use for zabbix.
It has 2 procs, 1GB
ram and sata disks and is in use since 10/2005
linux is debian of
course, kernel is:
Linux secsquid
2.6.13.4 #4 SMP Mon Dec 19 09:53:24 CET 2005 i686
GNU/Linux
i have one com port
on it and it is configured as COM1 in the bios, i am not able to set manual
addresses.
the addresses for
other devices in the bios are not using irq4.
/proc/ioports gives
me this:
secsquid:/proc# cat
./ioports
0000-001f : dma1

serial device.
