PCI Serial Ports

[user]

Am having a hard time (2 mo) setting up 2 PCI serial ports on a machine without serial ports. I have changed the script at /etc/rc.d/init.d/setserial to just have four manual entries. When I check the results, the entries that I have made for S2 and S3 are in S0 and S1. Whatever I do to this script doesn’t seem to have any effect on the way the ports get setup. Is there another script somewhere? The ports are operational in Windows on the dual boot machine.

Sorry, could you explain what do you mean by manual entries? Also, why are you activating four devices if you have only two? If there is two physical ports, it’s logical to have S0 and S1 instead of S2 and S3.

I don’t think its a good idea (or necessary) to modify the setserial script. What is the output of

setserial -g /dev/ttyS*

If the devices are detected, then udev will assign the nodes, assuming the necessary kernel module support is present.
