Universal 4.1 MLR»Web Installation and Operation Manual
WEB SETUP
TCP Control Commands
The Universal 4.1 MLR >> Web can be configured to accept ASCII control strings
over TCP. The TCP port used, TCP timeout and TCP enable check box can be found
on the Email/Network Setup page. TCP must be enabled for TCP control to work.
By default, when enabled, the Universal 4.1 uses TCP port 56 for control. A Telnet
client such as PuTTY may be used to test the TCP control interface.
