Hi, I am trying to implement communication between two PIC's through the USART.
I have been able to send a sigle Byte and received it safely. My problem is how to implement a packet data transmission and reception. i tried sending two bytes but the receiver always receives only the last byte.

Can any one help me on how to receive multiple bytes without losing the first bytes. attached are part of the transmit and receive codes in asm...
