I got minicom up (I was calling it miniterm, lol) but it doesn't seem to 
have a setting for translating LF to CR/LF.  The Mecrisp app on the 
launchpad only sends LF.

I also tried setting the "implicit CR on LF" option in Putty which 
doesn't do the trick either.

Just to recap, I have the rPi running headless with the command line on 
the PC through SSH using Putty.  The launchpad running Mecrisp is 
ttyACM0 on the rPi.  Through the Putty session I am running minicom to 
the launchpad.  Mecrisp seems to return "ok.<LF>" which marches across 
the Putty window until it wraps at the right margin.

Any suggestions?
