Hello,

I am developing a program that uses the parallel
port to read a 4-bit BCD number and return the
decimal value. I am accomplishing this by constantly
scanning the port and checking for the strobe (DV)
to go high. Once it goes high, the 4-bit word is
sent to "conv" to be converted to the corresponding
decimal value and printed to the screen. This is the 
problem. The "printf" marked with the ???? is needed
for the numbers to be printed out "real time". If
I do not have the "printf ("\n");" statement, the
program only writes to the screen AFTER I hit control-c
to stop the program. I am using DJGPP and RHIDE to
develop this program.

What I want is to print the data to the screen (and,
later to be logged in a file) in a row (ie. "123456")
instead of on a new line each time. I am sure this 
is not a problem with DJGPP or RHIDE but a simple 
"error" that I am making. Any help is appreciated.
Thanks in advance!
