hi,
I need to check whether the COM port on my motherboard is being activated correctly. I have a UPS connected to it, and the installed software refuses to acknowledge that there's anything there.
This is a SuSE 10 installation, on AMD64. I've checked in the BIOS that the COM port is "on".
Is there a tool in Yast for looking at COM ports?
I don't know if the yast hardware module can, but "setserial -g /dev/ttyS?" should show you which ports are activated. You could also use minicom or simply cat /dev/ttySx (replace x with the serial port's number) on one screen and then echo commands to it on another...
Check "man setserial" to find out how to configure a serial port... I think the SUSE portal also has an article on it...

Hi, typing setserial -g /dev/ttyS? gives: /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4 /dev/ttyS1, UART: unknown, Port: 0x02f8, IRQ: 3 /dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4 /dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3 Which seems okay? However, cat /dev/ttyS0 gives absolutely nothing, no chatter, nothing. I installed minicom, which also required a modem communication file thingie (?) loaded it up and configured the modem to /dev/ttyS0, but am unsure how to probe further to see if a) the serial port is configured correctly, or b) whether the UPS is trying to "say" anything. This UPS worked a treat on my SuSE 9.3 machine, but since upgrading to SuSE 10 (fresh install, new hardware) hasn't given a peep. Anyone got any experience with COM ports??
