Can PBP & 16f88 really do 9600,8,E,1

Thanks I've made some changes to my code and it is working sort of.

DEFINE OSC 8 			'Set oscilator speed to 8mHz 
DEFINE HSER_BAUD  9600		'Set Baud rate to 9600bps
DEFINE HSER_BITS 9		'Set to 9 bit mode
DEFINE HSER_EVEN 1		'Set Even Parity
DEFINE HSER_CLROERR 1 		'Clear overflow error automatically

OSCCON=%01111000 		'8 Mhz
ANSEL = 0 			'ALL DIGITAL
CMCON = 7 			'COMPARATORS OFF
INTCON = 0 			'Disable interrupts
TRISB = %00000100 		'SET PORTB RB2(RX) as input, others to OUTPUT
TRISA = %11111111 		'SET PORTA AS INPUTS

DATAIN VAR BYTE[12]		'Define DATAIN as a byte array (12 Bytes)  

loop: 				'Start of Communications Loop
HSERIN [str DATAIN\12]		'Receive 12 bytes into array DATAIN
HSEROUT [str DATAIN\12]		'Transmit 12 bytes from array DATAIN
goto looP			'Goto Loop

END

Now what I want to do is use a qualifier so that the Hserin waits until $AA is received before it starts filling the array. I also want the $AA in the array though? Possible?

So it should receive twelve bytes in all like this.

0xAA,0x10,0x00,0x00,0x00,0x20,0x40,0x61,0x10,0x01, 0x00,0x74

Does this look right?

loop: 				'Start of Communications Loop
HSERIN [WAIT($AA), str DATAIN\12]		'Receive 12 bytes into array DATAIN  
HSEROUT [str DATAIN\12]		'Transmit 12 bytes from array DATAIN
goto looP			'Goto Loop

I read that a delay may be required after the last send in the HSEROUT section or it may not transmit the last byte correctly?

You might want to get out of the habit of using the label LOOP: as ver 2.6 made loop a reserved word being used in the Do Loop routine.

I don't think so but I haven't actually tested this. Add the timeout and test.
