Is the serial port enabled in the BIOS?
I have looked and found nothing in the many pages of BIOS things
but
I could of missed it.
What model Biostar MB is this? All their manuals are online; older
ones especially included screenshots of the setup screens. Look for,
in the 'integrated peripherals' setup section the 'COM1' and 'COM2'
settings (the names might be different; I don't have a Biostar board
in front of me (got one at home, though, that I might put on the
breadboard and check out)).
This is from #setserial -a /dev/ttyS0:
[root@k5di ~]# setserial /dev/ttyS0 -a
/dev/ttyS0, Line 0, UART: unknown, Port: 0x03f8, IRQ: 4
Baud_base: 115200, close_delay: 50, divisor: 0
closing_wait: 3000
Flags: spd_normal skip_test auto_irq
This I think is good.
UART is unknown; no, this is bad. If the kernel can't detect the
type of UART (it will likely be 16550A or similar for virtually all
modern MB's) then it can't use the port.
On my own laptop, which does not have ANY serial ports:
[root@localhost ~]# setserial /dev/ttyS0 -a
/dev/ttyS0, Line 0, UART: unknown, Port: 0x03f8, IRQ: 4
Baud_base: 115200, close_delay: 50, divisor: 0
closing_wait: 3000
Flags: spd_normal skip_test auto_irq
[root@localhost ~]#
So setserial doesn't help troubleshoot this.
On the box with one serial port:
[root@itadmin ~]# setserial /dev/ttyS0 -a
/dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4
Baud_base: 115200, close_delay: 50, divisor: 0
closing_wait: 3000
Flags: spd_normal skip_test
[root@itadmin ~]#
UART is a 16550A, and works.
OK I do not have a manual about BIOS. If they have one I will get it!
I dropped to the Bios. Your telling me it is in Integrated
Periferals did the trick. I had to hit enter on one I never have before
and there was Serial Port 1 disabled! I got it set to auto and now it works!
I d/l the manual but it is a .exe file and I no windows to open it :-)
Thank You Lamar.
