Merci Mister e

But I would like to know another thing if I pass by the UART to register the information which goes into the PIC, how I have to proceed.

This line of program is good:

CTS = 1

SERIN PORTC.7,N9600,["@"],char 'wait for char. @ from the PC and store second @ in char... this is just a wait line, no received data is used

getserial:

Serin PORTC.7,N9600,char 'receive at 9600bps and store in variable char

write i, char 'write each received character to the memory


if char = EOM then
CTS = 0
Goto start
endif

i = i + 1

goto getserial

I am going to try with your configuration of the UART
Good day

Regards
