In general, you will need to make a buffer in conventional memory and move
the data to/from it. You may use the one used by DJGPP's library functions
if it's big enough (normally 16K but can shrink as small as 2K). FAQ section
18.2 talks about this.

It's a bit too complicated to write an example off the top of my head, but I
expect the FAQ will help you. If you still have trouble after reading it,
post again.
