Same player shout again
I am still in the same marmelade !
I have checked the hardware RX TX max232 seems good (no mix)
I will try to test as you said (transmit between PIC and laptop)
I suspect also that my programmer is not wonderfull
I must program sometimes 5 times to avoid errors
I must compare iniatial file from MCloader (16F874_20.hex) with the data burned in the pic !
I have tried with two differents PIC

for this week I will be out for 3 days, so, hold the line !
I lost already 3 days on this crazy thing, no problem because I am retired ! hi ...
