I'm using a 87C752 Microcontroller. The receiving end is the same type of switch. The distance between the two micros is only about 1 to two 2 feet. I'm planning to add RF modules which would transmit serial data. I only need to send the data once and receive it once. I want to ouput 8-bits in Mode 0, 8-bit shift register mode. This is the data that I have for transmission and receive. Please Change it in any way possible for it to work.

Transmission:
MOV SBUF, R0
HOLD: JNB 99H, HOLD ; TI
CLR 99H ; TI

Receive:
JNB RI, $
CLR RI
MOV A, SBUF

Thank you.
