When you attempt to start a communications program, you may receive one of the following error messages:
Error: port in use
OpenComm: Port already open
To work around this issue, follow these steps:
When you finish using a communications program and close the connection, Rnaapp.exe is still running and the port remains unavailable to non-TAPI programs.
Rnaapp.exe is left in memory to allow TAPI programs to open faster. Rnaapp.exe is eventually unloaded from memory (unless Dial-Up Networking Server is set to allow caller access), but it may take 10-15 minutes.
