thanks for the tips.
temp - lost by cut and paste !!
already implemented and tested.

some remarks anyway....

for the pic 4525 sending to goldcard one stream of 16 bytes takes 133,2 ms on the ossiloscope.
the pic 16F84 use the same oscillator of 4 mhz ( RB6/ osc) on the chipcard, and the same program but serin masked out - pic will send always the answer .
The same stream takes 149,6 ms , there is no match in the baudrate. why ?
it is not the pause between bytes send , normally 1 stopbit.
The difference is in each bit send. one byte takes 9,25ms.
i see a difference in high and low time for $55 - normally it must be a square wave !( for 4 periods at least )

I did'nt read this remark in another topic on the board

Harry
