Our HMIs do not support the Telnet protocol. However, since Telnet is an ASCII-based protocol, it may be possible to communicate to a Telnet client using the Free Protocol in EBPro. This uses the Macro feature to send and receive ASCII characters from the HMI using the Outport() and Inport() functions.
We have a sample project on our website that demonstrates how to implement
ASCII communications with a macro.

ASCII Serial Communications. Even though this references serial communications, it can be used over Ethernet as well.
