No.
YOu can't change the owner of a port in mid stream. When SLIP is running
C-Kermit performs an extensive negotiation with the SLIP driver in order
to share the port. There is no means for SLIP to start a negotiation
with C-Kermit. Therefore, the port cannot be shared.
If you think you might want to start a SLIP connection at some point,
then always start the SLIP driver before you call. Then use the SLIP
version of the port number. If you don't use SLIP, it doesn't hurt anything.
