PIC-to-PIC HSEROUT/IN

[Kamikaze47]

I want to send data from one PIC to another using HSEROUT/HSERIN, so as a first step I figured I would just send 1 byte and go from there. But i'm not getting the same byte out that i put in.

Transmit:

' PIC = 18F4550, 4Mhz External OSC, PLL results in OSC of 48Mhz

DEFINE OSC              48

DEFINE HSER_TXSTA       24h
DEFINE HSER_RCSTA       90h
DEFINE HSER_BAUD        2400
DEFINE HSER_SPBRG       25
DEFINE HSER_BITS        8

ADCON1=%00001111

main:
HSEROUT [$47]
pause 10000
GOTO main

Recieve

' PIC = 18F1320, 20Mhz External OSC

DEFINE OSC              20

DEFINE HSER_TXSTA       24h
DEFINE HSER_RCSTA       90h
DEFINE HSER_BAUD        2400
DEFINE HSER_SPBRG       25
DEFINE HSER_BITS        8
DEFINE HSER_CLROERR     1

ADCON1=%01111111

DEFINE LCD_DREG         PORTA
DEFINE LCD_DBIT         0
DEFINE LCD_RSREG        PORTB 
DEFINE LCD_RSBIT        2
DEFINE LCD_EREG         PORTB
DEFINE LCD_EBIT         3
DEFINE LCD_BITS         4
DEFINE LCD_LINES        2
DEFINE LCD_COMMANDUS    2000
DEFINE LCD_DATAUS       50
PAUSE 500

data_in                 VAR BYTE

LCDOUT $FE,1,$FE,2

main:
data_in=0
HSERIN 500,main,[data_in]
LCDOUT HEX data_in," "
GOTO main

Some tests:

sent   recvd
$47    $F9
$01    $F8
$FF    $FF
$E9    $FE
$AA    $FE

I'm lost as to what i've done wrong. Any ideas?

*edit* it must be something wrong with my transmit code, because using SEROUT2 instead on the transmit side works - but i need to use HSEROUT. Still lost.
