(I probably should have hit reply-all on this before...)

Just as an FYI, I had some of the same behavior when I first set my 
J6750 up with a serial line (null modem cable to a secondary machine)
Usually had to type the p/w 2 or 3 times to get it to 'take' in minicom. 
One thing I *did* notice was the *length* of the null modem cable and 
the proximity of the 2 machines seemed to make a difference (bad cable 
shielding maybe?) Just my 2 cents. (Running Kernel Ver. 3.12.6-2 at the 
moment)

...and like Dave A. mentioned, Xon/Xoff makes a difference too.

P.S. Now that it's up and running, and I usually log in with PUTTY or 
the STIcon graphics console, it's not a problem anymore. :-)
