There are three serial ports in my amd64 box; the integrated one, and a two port pci card. picprog does not work with anyone of them, and all of them have similar voltages. > > For example here picprog works without a problem on my normal PC, but > doesn't work on my laptop because the voltage of the serial port of my > laptop¹ is not high enough. I've examined the programmer with the osciloscope, and the amplitude of the pulses are about the same with both boxes (the amd64 and the 32bit one). In both cases, the pulses in the DTR line are about 12v of amplitud; there area burst in the read operation from the 32bit box, but only two or three pulses with amd64. The difference between ports voltages are about 0.5v in the worst case.
Let me know if I can help you in any way. Thank you, -- Fernando M. Maresca - - - - - - - - - - - - - Cel: 221 15 545 8196 Tel: 221 489 0466
