Bill,
I never tried MScomm with binary data but guess it's like VFP to SQL server's image type. Each byte value is converted to its hex char representation while sending and converted back to one byte on receiving end (ie: 255 goes as "FF"). If so get the data as string first and then write out in pairs :

for ix=1 to len(Str) step 2
=fwrite(hout,evaluate('0x'+substr(Str,ix,2)))
endfor

PS: A byte array might represent the actual binary data as is, a structure, a unicode string (strconv()) etc. W/o knowing the format what I said might be totally wrong.
