Even if you clip the voltages, a regular RS232 signal wouldn't work because the levels are inverted from the TTL signals. I've build my own cables from an FTDI USB/TTL 3.3V "cable". The converter sits in the USB plug, the other end is an open cable. Marcus von Cube Wehrheim, Germany http://www.mvcsys.de http://wp34s.sf.net http://mvcsys.de/doc/basic-compare.html |
