hi, I want to connect a circuit to the rs232 port, but my circuit has no power supply. It actually consists of a IR transistor. The purpose of the circuit is to convert Infra Red signals (with the correct timing of course) to rs232 level. I know it can be done because a serial mouse is doing it to : it uses the serial port as power supply. Can anybody tell me how it is done ? thanks Joris. |--------------------------------------------------------------------| | _ _ | | (_) | | JORIS BALLET | | _ ____ | |___ E-MAIL : GHGALAP@BLEKUL11.BITNET | | | | / \ | / \ | | | | | () | | () | (THIS ADDRES IS SUBJECT TO CHANGE | | __| | \____/ |_____/ DON'T USE AFTER JULI '91 ) | |(___/ | | | |--------------------------------------------------------------------| | PROGRAMMERS DON'T BYTE, THEY JUST NIBBLE A BIT. | |--------------------------------------------------------------------|
