Red Hat 7.1 kernel 2.4.2-2 recognized my modem and I had no problems with it. It's an internal ISA GVC 5634 BTS 56K set to PnP. Red Hat 7.2 knows its there. I can see it listed as unknown under hardware. But 7.2 refuses to have anything to do with it. Using minicom, I contacted the modem via ttyS2, but when I try to telephone: minicom -d 9866722 I get a segmentation fault in both xterm and on the command line. I then created a link, ln -s /dev/ttyS2 modem but it made no difference. Duh? Maybe I'll reinstall 7.1 and try to find out what it did that 7.2 is not doing. Anyone got any ideas?
