Greetings PICers, This is completely OT but if anyone knows of any software written to somehow use the parallel port or the serial port on a PC as a logic analyzer. I only need to have a single channel and need to be able to capture and save the incoming data stream for a period of atleast 5 secs. The data stream is being clocked at about 40 KHz. Please send responses back to sheikh@erols.com. Thanks a bunches. Shahid
