I don't understand why people mess with SCP when all you have to do
is write a simple ASCII interface for the oopic. Which is easier,
trying to decipher this "\0V42J144H36L03N", or this oopic code, by
way of example ...

====================
Do
' process incoming keypresses
if (com1.received=1) then
key = com1.value
' convert small to capital
if (key > 97) then key = key - 32

if (key=ch_S) then
call stop ' "S"
call play1
end if

if (key=ch_F) then call forward ' "F"
if (key=ch_A) then call accel ' "A"
if (key=ch_D) then call decel ' "D"
if (key=ch_B) then call backup ' "B"

if (key=ch_H) then call half ' "H"
if (key=ch_L) then call turn_left ' "L"
if (key=ch_R) then call turn_right ' "R"
if (key=ch_K) then call brake ' "K"
call report
end if

Loop
