Christian Vogel vogelchr at vogel.cxHi Dieter, Zitat von Dieter Spaar <spaar at mirider.augusta.de>: > your own level-converter, you can for example use the MAX232 IC. The > MAX232 is for TTL level (0V and 5V), I think there is a variant for > 3.2V available, however I am not 100% sure. Maxim alone has about a dozen variations of the MAX232 (max3232 for 3v3, e.g). It's much easier to directly go from USB to TTL/3v3 serial ports, the basic breakout boards from Sparkfun (e.g. http://www.watterott.com/de/FTDI-Basic-Breakout-33V) seem to be fine and sell for ?12. Haven't used them on a C123-phone, though. Chris
