How do putc() work?

Hi everyone! Although I have look for this function in PICC folder but I can't find this function. Can you tell me how to see inside this function? Thanks!

Hello all,
I used this blocking technique in my code and I want to create blocking putc().
using byte and bit defined for TXIF i added this in my code.

putc, already blocks. It waits if the character can't be accepted by the UART. However the UART will merrily transmit into an open line, so disconnecting the lines won't stop it.

You could make it check for 'line break', by verifying that the RX line is high before sending. This can simply be read as an input.

Thanks Ttelmah,
This made some points clear about transmission. I will try it. Thanks.
