INT 60 - FTP Packet Driver - PC/TCP Packet Driver Specification
   The handler for the interrupt will start with a 3-byte jump instruction,
   followed by the ASCIZ string "PKT DRVR".  To find the interrupt being used
   by the driver, an application should scan through interrupt vectors 60h to
   80h until it finds one with the "PKT DRVR" string.
