Hi

According to
wiki.segger.com/RTT#TELNET_channel_of_J-Link_software

you can send a configuration string within the first 100ms of connecting via telnet.
And both JLink RTT Client and PuTTY are mentioned as examples.

How would this work in practice ?

I can't get any of those clients to properly configure the RTT channel to 1 using
$$SEGGER_TELNET_ConfigStr=RTTCh;1$$

I have also tried MobaXterm which supports macros but that is not working either.

The only available telnet 'client' I could get to work was Telnet Scripting Tool 1.0 which supports waiting for specific incoming text before sending anything.

Any advice ?

Thanks!
