RUTX11 - Serial Over IP

[interserver]

Hello,

I am having an issue with double commands being issued over serial.

See screenshot

I am using a USB-to-serial console cable (StarTech.com Cisco USB Console Cable)

The attached device is a Cisco switch. I tried different switches as well.

I tested with a few Teltonika firmware versions 7.16.2 and 7.20.1.

I tested with 2 different RUTX11

Here are the configuration screenshots:

I have tried every option as well

Greetings,

This appears to be an echo issue, and since TCP Echo is disabled on the RUTX11, it could be originating from the Cisco side or due to the Telnet session.

Could you please try connecting using a different application (for example, PuTTY or MobaXterm) and check whether Ctrl + C works correctly and whether the commands are still duplicated?

Best regards,
Justinas
