I've given it another try, using seyon instead of minicom, which turns out to be a much better tool to diagnose modem problems. I've noticed that in Windows the card installs with ioport=0x3f8, irq=10, COM1 is on 0x238 instead. I've tried the same on Linux without any luck. What I found strange: if syslog says kernel: tty03 at 0x02e8 (irq = 10) is a 16550A and I call setserial /dev/ttyS3 irq 10 then seyon cannot find any modem at all, with other irqs it does not complain but the modem does not work either. I've also looked into the BIOS settings but did not find anything special, just floppy, sound, parallel port. My Tecra has a DVD-player and an MPEG-II decoder instead of an internal modem, but they do not occur in the BIOS settings. When I use setserial to set the irq to 0, then seyon immediately echoes what I type and the modem answers, so it really looks like an interrupt problem?! --Micha |
