Hi

I am writing an application where I need following features:
* Running on DOS with DOS extender (Right now testing with HX Dos extender)
* A lot of memory. > 1 MB
* TCP/IP stack
* Writing own ISR

I have some troubles combining all this.

If I want to use the TCP/IP stack comming with DMC (Winsock) I need Win32
memory model. But that excludes the use of dos_getvect and dos_setvect :-(

I tried to compile WaterlooTCP with DMC, but I have the same problems with the
interrupt vector functions, as I need "flat" memory model which is the
Waterloo TCP's name for Win32 memory model. This was my original favorite, to
avoid winsock.
Waterloo TCP: http://home.broadpark.no/~gvanem/

Before I try to write my own get_vect and set_vect functions, I would like to
hear if I am on the wrong track.

What you could do is get the full DMC package, which includes the complete 
library source. Then, you could modify it to suit.
