Problem:
   I have a program that needs to be run in an SS!=DS environment and
I am trying to use the write function; however, it does not seem to be
working.

Response:
   The write function will not work correctly in SS!= DS in text
mode. It should work properly in binary mode. In text mode, write()
builds a buffer on the stack to do LF to CR/LF translation. It makes a
call to stackavail() to make sure it does not overflow the stack; this
call is what prevents it from working with SS!=DS.
   This is program design for this product.
