c++ telnet server for esp32

I'm looking for a telnet server for esp32.. very basic, just accept the tcp and say hello and buffer or return client data. The only ones I could find were for computers...

start a WiFiServer at port 23 handle the clients and that is all

see the WiFiTelnetToSerial example

It's too complex to start with and I have bern puking... I understand concurrent tcp connection, but what was point of two serials? Anyhow I screwed it up because I got a a Java net socket exception. I'll post code soon, it embarrassing.
