• n=3 : With a Telnet connection, overrides the clientʹs

will also be edited to simply pass CRs to the server on the
host port.

Interval to terminate a TCP connection when no in or

broken TCP session can result in the modem being left with a TCP
half-open connection that can only be terminated with a reset.
