[Mono-dev] Terminal config for mono csharp shell?

Sun Jun 7 04:06:15 UTC 2015

Funny you should mention python.  I've ported 3.4.2 to Android and the interpreter runs without issues; no cursor jumping and no stty sane needed after exit.

In my env TERM=linux but I have other options...if that would help.  I'll take a look at the routines you mentioned, but i'm kinda hoping to find a way to resolve this without (moe) hacking at source code.

Thanks for the pointer in the right direction.
