Are you able to open the unit and locate the UART or the multi-IO chip that's actually being used? You may be able to track down a datasheet for the part, which would help in working out the "right" thing to do. > I've tried upping the DELAYs in sio.c (as recommended by Bruce) but it > doesn't help 2.2-GAMMA. This includes the one between the setting of failures[4] and the test for setting failures[5]? This would be the critical one IMHO. You could also try reading the IIR several times, in the hope that it just takes some encouraging to go away. > Back into the sioprobe() code again, I guess.... You could try forcing the probe to succeed, and see if the port works properly. It's almost worth having a flag to do this. > ...sjs... -- ]] Mike Smith, Software Engineer msmith@gsoft.com.au [[ ]] Genesis Software genesis@gsoft.com.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control.
