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. Dave L. 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. :-) -- Dave Land Land Computer Service xmechanic@landcomp.net ICQ: 676030523
