That only works if there are only three wiresand no handshaking. What if there is DTE/DCE and so on? But I think in this case it is just a three wire connection but still there is room for errors like for example is one of them a TTL level and the other RS-232. Some times you can mix the two, sometimes not. -- Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
