Serial Telnet While in Genisys ATCS Mode
When the WAG is configured with a serial interface of either Genisys ATCS protocol (Office or
Field), any attempt to establish a TCP connection to the Serial Telnet port will be disallowed.
Such a connection attempt will cause the TCP connection to be established and then immediately
be disconnected. The TCP connection is allowed for a brief period of time to log that a
connection was attempted and disconnected.
TCP connections are disallowed to the WAG's serial interface when the interface is configured for
Genisys because the assumption is that the interface is being used for important communications
to other serial devices. This prevents the operator from interfering with the communications
assumed to be taking place on the serial interface.
Serial Telnet While in HDLC Mode
When a TCP connection is attempted to the serial interface of a WAG that's configured for HDLC,
if the WAG isn't configured for Persistent Serial Tunnel, the WAG will immediately disconnect the
TCP connection.
