hi everybody .

here its is what i want to do exactly and wat i got .

i want to connect 4 pic16f84a to 1 pic18f4550 serially . and every pic16 send
its portb value to pic18 serially . then pic18 send the value to my pc usb . so i write the code for pic16 and test it on my pc serial port and its working fine and send the right value . what when connect to pic18 , pic18 send wrong values . here is my code and hope to find anything wrong ?
************************************************** ***

' pic16f84a code
include "modedefs.bas"
define osc 4
TRISB = %11111111 ' portb all input
PORTB = %00000000 ' portb 0
TX VAR PORTA.2 ' transmmit
B0 VAR BYTE ' var for store portb value
B1 VAR BYTE ' var for store portb value

start :
B0 = PORTB
PAUSE 100
B1 = PORTB
IF B1 = B0 THEN start
IF B1<> B0 THEN SEROUT TX,N9600,[B1]
B1 = B0
GOTO start
