6 Use a host program such as Telnet to receive these TCP logging messages
(Note: Other programs such as HyperTerminal are also used to monitor
TCP connections). See below.

Telnet Client: You can use a Telnet client connected to the TCP port
(log1 = 4010, log2 = 4011) rather than the default Telnet port (23).

Telnet Session: If there is a Printer at IP address 192.37.23.155 (and
you have configured log1 for TCP logging), then you could initiate a
Telnet session from a DOS window of a PC by entering Telnet
192.37.23.155 4010.

Log Messages: All system log messages would then be displayed in
that Telnet session window. (Note: This is a one way connection for
logging only. Any input to the Printer on this connection is ignored.)
