Boot output looks fine. Cables are normal nullmodem. I can interact
using minicom with the firmware, i.e. typing "BO

Yes, in the PDC everything still seems fine.

But as early as in the IPL I can't paste a string without
characters dropping (which is how I first noticed the issue, since
that's where I normally do this to select a kernel to boot). So did the
IPL change as well, then?

(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. :-)
