HC-12 wireless transceivers

Has anyone used the HC-12 wireless RS-232 modules on ebay? My modules seem to work fine with Arduino but I am having no luck using a 16F628A/16f616. Very simple code below returns

Transmitter Code 16F616:
Tx:
SEROUT PORTC.5,6,[2] 'sends 2 to the HC-12 every 3 seconds
PAUSE 3000
GOTO TX

Receiver Code 16F628A:
OVER:
SERIN2 PORTB.2,16468,3000,OVER,[V1]
IF V1 = 0 THEN GOTO OVER
SEROUT PORTB.5,6,[#V1,10] 'Output to serial Monitor
GOTO OVER
