       1. It is impossible to send a '\032' character to a device, even if
   it was open'ed in 'O_BINARY' mode.  This made it hard to send raw data
   to my printer, or to redirect raw data from printer to disk, & vice
   versa.  [...]

I believe this is caused by MS-DOS, not MS C 5.0 --
One of the peculiarities of MeSsy-DOS is that file handles have a primitive
binary/text mode.  The only thing that the binary mode does is when writing
to a device it is impossible to write a ^Z (0x1A, 032) character.  Guess in
which mode the device files (PRN, AUX etc.) are as default ?

You need to do a IOCTL to change the file handle to binary mode and all will
work correctly.  However, I think that a C stdio library should be smart
enough to do this on it's own if the file was opened with O_BINARY (or "wb",
if you are using the buffered I/O functions).
