I tried two of the black boxes once sold at c-base (BenQ boot cable). I'd rather try to find and add the Vcc_3V3 line first before adding a pull-up on Rx. > an other trick is to use a transformer 12volt power adapter not a > ac/dc switching power adapter and if you do this on your laptop, > unplug it from ac to run on battery power. > with some devices i got better results in this way. Noise on the ground line? I tried a lab power supply instead of the 9V wallplug, no avail. > i'm still looking for a very good 3.3v serial adapter, the prolific is > not the best one. What about the OTI6858 used in some mobile phone data cables? Unfortunately mine broke recently. I ordered a new cable and got a PL2303 inside (but with a Vcc wire). I got a FTDI FT2232D DIP module here as well - meant to be used in a JTAG/RS232 adapter sometime. But this one still misses the adapter board.
