I believe that it was this group that included the PC reading a switch thread...... Anyway, I just came across an article in 12 July issue of Electronic Design that has a circuit using the serial port (yea, I also thought of that :-) ) and even included a schematic and little (ugh) basic program to read the port. Thought I'd pass this along in case anyone still cares

But did you look at that code? Even for BASIC it's scum. They open the serial port for output. If DSR is not asserted, the program falls into an error trap (!?) otherwise it sets a variable. Somebody must have been using this as a classic "bad example" for a programming class. Oh, well -- it's good entertainment. ---------------------------------------------------------- Gordon S.
