Int 61 Fn 22  u - Pc/tcp Kernel V2.05+ - "net_getdesc" - Allocate Network  [N]

   AH = 22h

Return: CF clear if successful
       AX = network descriptor
   CF set on error
       AX = error code (see #2990 at INT 61"FTP Software")

Note:  the descriptor will be an integer in the range 00h-1Fh, and a DOS call
     is made to allocate this as a file descriptor.  Hence a number may
     not refer to a PC/TCP network descriptor and a DOS file handle
     simultaneously.
