assembly code and hyperterminal

Muneir Abdalla

hello guys, i have this code at the end of the post, which control 8 devices over bluetooth.
im trying to figure out what command that i can send over hyperterminal to activate a port or a pin. to my understanding if i want to set pin1.0 i should send 'A'>0AH>31H is that correct?

any kind of help is really appreciated.
here's a portion of the code

LOAD1   EQU     P1.0
LOAD2   EQU     P1.1
LOAD3   EQU     P1.2
LOAD4   EQU     P1.3
LOAD5   EQU     P1.4
LOAD6   EQU     P1.5
LOAD7   EQU     P1.6
LOAD8   EQU     P1.7
