Hi Fred, thanks for the answer. Oh yes I try'd all, that is possible with the pcbug342 but without success.

I had the same problem with an A1, in this case it was stuck at 0x0D. hbdl would NOT set the config, but I was able to do it with dl from Win95 run in full MS-DOS mode. Even this was problematical; dl would invariably hang the computer once or (...) (26 years ago, 2-Apr-98, to lugnet.robotics.handyboard)
