- We have the card that Mike is describing on a SparcStation-2.
- However, we seam to have some problems with it. We use the
- loadable device driver that came with the card (STC).
- We use the serial lines for dial-in modems.
-
- The problem is that sometimes when people logout they leave a
- process hanging on the port in the state <exiting>.
- From then on, the only thing that we found to bring that port
- back to life is to reboot the machine.
-
- The problem is very elusive, as we couldn't make it happen on
- purpose. It only happens sometimes and not necessaraly to the
- same people.
-
-
- If you know of a solution to this problem we would be happy to
- hear about it.
