Modem Set-up Problem

Hi,
I'm trying to get my modem to work on my thinkpad 755C under Slackware 96 linux, but I am unable to do so. I have made sure that all of the proper parameters were set, ie., /dev/cua0 is linked to /dev/modem. And the irq is set to 4. Upon boot linux even says "serial or modem detected".
    However, when I run minicom it says that it initializes the modem, but the modem responds to nothing. When I run seyon it can't initialize. Could there be any wierd quircks about Slackware? Is my modem, Megahertz XJ4288, supported (I think it is.). Any help would be greatly appreciated.

Thanks,
Ryan Harbert

Try relinking your /dev/modem device to /dev/ttyS0 and not /dev/cua0.  Also, are you trying to run seyon as root or non-root?  If it's a non-superuser, minicom or seyon probably won't have permissions to open the device in question.  Login as root and try to run seyon or minicom on the device you have selected.  You can set minicom to use /dev/ttyS0 or /dev/ttyS1 directly until you are sure which port is which before linking to /dev/modem if you want.  If you need to be able to run the comms programs as a non-root user, you'll probably need to add yourself to a group which has access to the device(s) you want to access, say uucp or modem - depends on your flavour of Linux.
