Hi Bean,
I do attach a 10k resistor on /MCLR to vdd.

The purpose of my code is to send data to a COM port by routing through MAX232 driver.
The same code is doing by BS2 very well, and doing correctly on SX debug mode.
Here is code below, sending out characters a~z via Max 232, it's just a test.

-----------------------------------------------------------------------------------------------
Start:
tris_a.0=1
tris_a.1=0
tris_a.2=1
tris_a.3=1
i VAR Byte
char VAR Byte (1)

i=0
inchar(0)=0

Main:
   	char(0)=i+"a"
	SEROUT RA.1 ,T2400,char(0)
	PAUSE 200
	toggle rb.0
	i=i+1
                i = i // 26
GOTO Main
