Its not the serial ports


b var byte

include "modedefs.bas"

for b = 1 to 100
SEROUT PORTB.6,T2400,[#b]
next


Counts as you would expect, on the pic simulator with the code complied for the F84 and simulator set for F84 works great, set compiler to 877 and simulator to the 877 it delivers garbage.

This is telling me that there may be something wrong with my basic compiler
in the include files ?????

this should give 12345 etc but give junk with the 877 selected
