Thanks Ray! ray@xxxxxxxxxxx said: > I'm assuming the modem is attached to a serial port Yes, has been for years. ls -l /dev/modem lrwxrwxrwx 1 root root 10 2006-07-18 20:29 /dev/modem -> /dev/tts/1 sudo /sbin/setserial /dev/ttyS1 -a /dev/ttyS1, Line 1, UART: unknown, Port: 0x02f8, IRQ: 3 Baud_base: 115200, close_delay: 50, divisor: 0 closing_wait: 3000 Flags: spd_normal skip_test auto_irq ttyS1 used to be the place from which to run the modem I know for sure when I had kppp installed. sudo /sbin/setserial /dev/ttyS2 -a /dev/ttyS2, Line 2, UART: unknown, Port: 0x03e8, IRQ: 4 Baud_base: 115200, close_delay: 50, divisor: 0 closing_wait: 3000 Flags: spd_normal skip_test auto_irq Now this is the output in Fed4 at ttyS0: /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 To which modem etc. connects properly. Doing sudo /sbin/setserial /dev/ttyS1 uart 16550A I get heisspf@~:$ sudo /sbin/setserial /dev/ttyS1 -a /dev/ttyS1, Line 1, UART: 16550A, Port: 0x02f8, IRQ: 3 Baud_base: 115200, close_delay: 50, divisor: 0 closing_wait: 3000 Flags: spd_normal skip_test auto_irq With microcom which I snatched from my DSL box where again the modem is working properly: sudo /usr/local/Microcom/microcom Try /dev/ttyS0 /dev/ttyS0 not found Try /dev/ttyS1 /dev/ttyS1 not responding (after I set the uart 16550A) Try /dev/ttyS2 /dev/ttyS2 not responding Try /dev/ttyS3 /dev/ttyS3 not responding In this kernel 2.6.16 there is no more ttyS0 instead /dev/tts/1 to 3. I know it was working with kernel 2.6.14 but now it does not even work with 2.4.31. Something broke somewhere. Fedora4 does not run setserial neither does DSL.
