Simple Serial Test Tool

This is a simple set of serial test tools. The terminal emulation is basic - can't turn off local echo or change the font, but it does work.

this works!

I've been trying various serial apps (stty screen, tio, goSerial) to connect to my serial device. with no luck. all I needed was to keep RTS inact. This tool made it work for me.

Needed a tool to monitor two serial ports at the same time for my ESP32 projects. Worked perfectly, just select the ports and away you go!
