Well, I must admit I don't know how to check that. Do you? Well, I can 
probably find out myself. I have just made a program that takes 
parameters from commandline, and if I try to redirect its output, the 
pipe is treated as a parameter, so I could actually use the information.

Well, I think is is a bit more complicated than that. I think Jim Leonard 
is on the right track. Function 44h/int21h and its subfunctions seems to 
be useful, and I will try to play with it and see if I can come up with 
something.
