  i.e.
  `ax=0x4409, int21' gives dx&0x1000 = 1 for drive is remote. = 0 for drive is
local, carry = 1 for no such drive;
  `ax=0x440a, int21' gives dx&0x8000 = 1 for file with handle bx is remote. =
0 for it is local, carry = 1 for no such file;

but my interrupt book says that these two interrupts only exist if networking
software is running on the PC. How can the program find if networking software
is running on the PC?
