INT 21 - PC/TCP IPCUST.SYS - RESET CONFIGURATION DATA READ POINTER

	AX = 4402h
	BX = file handle referencing device "$IPCUST"
	CX, DS:DX ignored
Return: CF clear if successful
	    AX destroyed
	CF set on error
	    AX = error code (01h,05h,06h,0Dh) (see #01680 at AH=59h/BX=0000h)
Notes:	there are a total of 378h bytes of configuration data for IPCUST.SYS
	  version 2.05.	 If less than the entire data is read or written,
	  the next read/write continues where the previous one ended; this
	  call and AX=4403h both reset the location at which the next
	  operation starts to zero
	v2.1+ uses a new configuration method, but allows the installation
	  of IPCUST.SYS for backward compatibility with other software which
	  must read the PC/TCP configuration
