I have seen some LPT ports that can not supply enough current to work with the standard bipolar keying circuit. Measure the current flowing into the base of the transistor and compare it to another c
Follow-up: Jim was right on with the modes - apparently the default mode is uni-directional. ECP and EPP modes are bi-directional - allowing the paddle input to be detected. Next problem: we are trig
What is the difference betweeen ECP and EPP ? Tnx, zoli ha1ag _______________________________________________ CT-User mailing list CT-User@contesting.com http://lists.contesting.com/mailman/listinfo
