The command: cat /proc/tty/driver/serial <cr> on my system didn't show any types of serial cards known to the kernel. What it did show was serial info results like ports and irqs and uarts were unknown. After having had a look at that output which writes to stderr I'm surprised anything on this system including the litetalk is working at all. The litetalk is there and does show up correctly though. If this is all that red hat 7.0 can do towards getting a siig 20x pci serial card contacted I'm stuck. Jude <jdashiel@shellworld.net>
