However, I think what you are looking for is a general approach. The approach you should take is that you have to permanently assign lines from the com- puter to the dataswitch as outgoing only. This means that the "getty"s must be turned off. Then when you "open" the line, DTR goes up and the switch responds(hopefully) with CD. This completes the open and then you either do uucp/cu stuff or your own. Hope this helps. cbosg!sparky alias Norm Thompson
