Hi, first of all, thanks for the answer. Second: I don't have the pickit programmers, nor the more expensive ones from MPLAB. I've a velleman k8048. The profilic doesn't freeze, I can use the programmer with it very stable. Also, I don't have Windows (you know why), but will MPLABX do the job? I've that installed...
> I assume that you properly blocked all power pins and RESET on PIC. You mean I send the pic 5V? I do, should I do something with the MCLR? Because I can do a "hello LED" (parody on hello world) without problems. I don't use an X-tal/oscillator. I've an old osciloscope, I hope it still works, what should I measure and what wave should I get?

Do you have oscilloscope or logic analyzer to look at RxD on PIC? I assume that you properly blocked all power pins and RESET on PIC. 16F887 has ICD so I would try to run debugger using MPLAB and ASM code from SDCC.
