Hi,

i would like to know how to make PC and the 8051 (MCBx51) board to communicate with each other.

I tried with a small program and it didnt work.

below is the program

mov tmod,#20h
mov th1,#-6
mov scon, #50h
setb tr1
again: mov sbuf,#55h
jnb ti,$
clr ti
sjmp again
end

i tried to see the bit 55 in the hyper ermianl window and it didnt work.

also I want to know how we can make 8051 to receive input through hyper termianl window?
