Conversion of hex pairs to chars...best way?

[T. R. Ponn]

Richard...thanks, but I failed to mention that these files are typically 
binary (which of course, isn't a problem) or come to my app in the form 
of a Motorola S-Record or Intel Hex.  My app opens these files, does the 
necessary checking..prepares them as packets...then sends them via write 
to socket to a remote embedded system we've designed.  So, I don't 
believe the base64Encode/Decode will do the job for me.

BTW...we're really excited about this new product and my app has been in 
beta for a few months now...I just can't stand *not* tinkering.  Much 
praise to Rev and this list...without both, we wouldn't have been able 
to do this!  I will be posting our app to the Rev site a soon as it's 
released.

Best Regards,

Tim Ponn
