Wy are you doing this? The baud_base of a 16550a is 115200 unless this is very strange hardware indeed. The baud base is just used by the serial driver to choose which divisor to set for a requested speed. A baud base of 9600 with a requested speed of 9600 give a divisor of 1, which will make a normal 16550a run at 115200. It won't see anything coming over the cable at 9600, or maybe a little garbage. > setserial -a /dev/ttyS01 > setserial -a /dev/ttyS02 > setserial -a /dev/ttyS03 > setserial -a /dev/ttyS04 > > root@webby:root# ./serial.ports > /dev/ttyS01, Line 1, UART: 16550A, Port: 0x02a8, IRQ: 3 > Baud_base: 9600, close_delay: 50, divisor: 0 > closing_wait: 3000 > Flags: spd_normal > > /dev/ttyS02, Line 2, UART: 16550A, Port: 0x02e8, IRQ: 15 > Baud_base: 9600, close_delay: 50, divisor: 0 > closing_wait: 3000 > Flags: spd_normal > > /dev/ttyS03, Line 3, UART: 16550A, Port: 0x02f8, IRQ: 15 > Baud_base: 9600, close_delay: 50, divisor: 0 > closing_wait: 3000 > Flags: spd_normal > > /dev/ttyS04, Line 4, UART: unknown, Port: 0x03e8, IRQ: 15 > Baud_base: 9600, close_delay: 50, divisor: 0 > closing_wait: 3000 > Flags: spd_normal > > I have constructed a null modem cable, I have tested it between COM1 and COM2 on my windows workstation, and between COM1 and /dev/ttyS00 successfully. e.g. a 50K + test file with no apparent garabage or corruption using 9600 8 n 1 I was successful in going from windows to linux and from linux to windows without issue on /dev/ttyS00. /dev/ttyS00 is the motherboard serial port. Probably because you didn't mess with the baud_base. > > The cable pin out is db9: > > 2 -- 3 > 3 -- 2 > 4 -- 6+1 > 5 -- 5 > 6+1 -- 4 > 7 -- 8 > 8 -- 7 > > > On windows I am using Terra Term Pro, a freeware serial/telnet client.

Or try if Wine will run Terra Term Pro. Lawson -- ---oops--- ________________________________________________________________ Sign Up for Juno Platinum Internet Access Today Only $9.95 per month!
