i am a bit of newb. but i don't understand why you are using a char instead of an int
i tried that, same results. the following does not work
for (int a=0; a<inByte, DEC; a++){
like it works for serial print. thanks tho.

my apologies, no offense intended, i was really really tired last night when i posted, and this was an honest mistake.
