IMHO, the best way to do it is to use the DJGPP Filesystem extensions,
which are specifically provided for such cases.  The libc reference 
describes these functions.  Once you have a working low-level interface 
to serial or tcp/ip link, all that you need is to define a bunch of 
handlers for basic functions like open/close and read/write, and install 
them so that they get called by the DJGPP I/O functions automatically.

Huh?  Doesn't DJGPP give you long filenames on Windows 95?  And as for 
fast access to files on breakpoints, I have a small patch for GDB that 
makes this so fast you wouldn't believe.
