I've recently tried to use two different brands of 8-port PCI serial cards in an FC2 machine. It didn't work and I was forced to downgrade the machine to FC1. This is a heads-up if you want to try anything similar. The machine has two on-board serial ports, ttyS0 and ttyS1, and a PCI modem card, ttyS4. When the 8-port card is added to the system, it fails to notice the modem and starts numbering ports with ttyS4. But it only goes to ttyS7 and then wraps around. It does notice that 0 and 1 are already in use so it allocates ttyS2 and ttyS3. Then it stops, giving me only six new ports and losing the modem. With cooperation from one of the vendors, we tried to work around the problem using setserial. All attempts to assign any of the new ports to ttyS8 and above failed. While the FC2 distribution creates device nodes for ttyS8 and many others with higher numbers, it appears impossible to actually use those nodes. If this is a known issue, is it expected to be fixed with FC3? -- Dave Close, Compata, Costa Mesa CA "You ain't goin' nowhere, son." dave@xxxxxxxxxxx, +1 714 434 7359 -- Grand Ole Opry manager to dhclose@xxxxxxxxxxxxxxxxxx Elvis Presley, 1954
