Hi Vasile,

> The benefit of excel timers computation !!!

  :-))

  If anyone don't know where's the file, or is still sleeping (it's 
monday after all):

  Not with PICs, there's an amateur radio comm. (AX25) that uses the 
PC and some cheap components on the serial port (in 1200 baud): RX 
via lm741 and a simple R-C network for TX. The R-C network transform 
the ±12V square into a small sine for the transceiver. The frecuency 
are into 1KHz and 2.5KHz (it's BELL 102).

  There're some code in the piclist about that, 1200 baud modem, to 
do with a pic. But I thinks that this is not for you, you need a 
laarge sweep.





Regards, Javi
