Feature request: Prevent printing of escape sequence

[sslupsky]

I've been working with your command line code. Thanks for posting this.

I noticed a peculiarity regarding the history. It took me a while to understand that you are using a character from an escape sequence for the up and down arrows. As a result, the escape sequence is echoed to the screen briefly.

It would be nice to filter out the escape sequence so it does not appear in the serial stream.

Hi @sslupsky. I won't be spending time on this library, but I will leave this issue open for anyone to pick-up.
