Hi,

Just wonder what is the maximum baud rate for PIC16f876 using hardware UART?

#use rs232(baud=???, xmit=PIN_C6, rcv=PIN_c7)?

For this they invented something called a 'data sheet'.......

The PIC16F87X data sheet, Table 10-4 lists several examples of settings, including the minimum and maximum baudrates. With a maximum clock speed of 20MHz, BRGH=1 and SPBRG=0 you get a maximum baudrate of 1,250,000 (1.25Mbaud).

I think you will find the PC that you are talking to is going to be the limiting factor. Especially if it is a Windows program using the standard serial drivers.
