I added a printf before the _dpmi_int() to print out all of the 
registers. All parameters were correct  but the interrupt returns 
immediately with the flag register set to 0x247 on my machine CF 
indicates an error condition. Unfortunately I do not know which bit of 
the flags is CF. And AH remained 0x86 which means that there was no 
'wait in progress', in which case AH would be 0x83.
