Thank you to the people that have responded so far.

I'll proceed with the assumption that effort will be required beyond plugging in the cards. My current assumptions are:

1) The OS will probably see the cards but there is risk of needing to figure out how to use modprobe if the cards are not seen.

2) I should plan on 5-10 minutes to reinstall Device::SerialPort. I didn't expect this but I had to install Device::SerialPort on a box this morning. As I watched the build messages on the screen it appeared that the install was system configuration dependent.

3) I am assuming that reinstalling Device::SerialPort will give me a new, clean configuration. If the new install won't cleanly cover up the old install then the old configuration might hang around to cause problems.

4) It sounds like the port names might be unstable but the "setserial" command in the first response should fix them.

Thanks,
Bruce
