INT 60 U - INTRSPY/CMDSPY v1.0 only - API
Program: INTRSPY is a script-driven debugger included with the book
	  _Undocumented_DOS_.
InstallCheck:	determine that a) the handler is an IRET instruction, and
	  b) the signature 0Dh "INTRSPY vN.NN" immediately precedes the handler
Notes:	INTRSPY will hook the first available interrupt in the range 60h-67h.
	If INTRSPY is installed, the DWORD immediately after the IRET stores
	  its entry point (see #03275)
	INTRSPY v2.0 (included with the second edition of the book) no longer
	  supports this API
Index:	installation check;INTRSPY

(Table 03275)

INT 60 U - PC/370 v4.2 - ???
	???
Return: ???
Program: PC/370 is an IBM 370 emulator by Donald S. Higgins
Range:	INT 00 to INT FF, selected by patching the executable
Note:	the documentation includes instructions for patching the system for
	  another interrupt
SeeAlso: INT 2F/AX=7F24h,INT DC"PC/370"

INT 60 - JPI TopSPEED Modula-2 v1 - PROCEDURE ENTRY TRAP
SeeAlso: INT 61"JPI"
--------N-60---------------------------------
INT 60 - FTP Packet Driver - PC/TCP Packet Driver Specification
Range:	INT 20 to INT FF
Notes:	The handler for the interrupt will start with a 3-byte jump
	  instruction, followed by the ASCIZ string "PKT DRVR" (the
	  terminating NUL is significant).
	To find the interrupt being used by the driver, an application should
	  scan through interrupt vectors 20h to FFh (60h through 80h for
	  v1.09- of the specification) until it finds one with the "PKT DRVR"
	  string.
	AH values of 80h to FFh have been reserved for user-defined additions.
