PortServer II Telnet negotiation options

When connecting from the PS II via telnet to a outside telnet server what information can used on the remote side to allow for a reconnect. The telnet server I’m connecting to allows reconnect by user, IP or MAC. The problem is the IP and MAC are all the same when coming from the PS II. Does the PS II have a way of sending the com port being used via telnet negotiation like TLN?


I’m not aware of any way this can be done, since there are no outgoing port identifiers in a telnet session as far as I know.

I ran a port sniffer and found out that the PS II does support Telnet TLN which includes the port number.
