Line 3: A packet driver uses an [[INT (x86 instruction)\|x86 interrupt number]] (INT) between {{nowrap\|60h .. 80h.}} The number used is detected at runtime, it is most commonly 60h but may be changed to avoid application programs which use fixed interrupts for internal communications. The interrupt vector is used as a pointer (4-bytes [[Endianness\|little endian]]) to the address of a possible interrupt handler. If the text string "''PKT DRVR''" is found within the first 12-bytes immediately following the entry point then a driver has been located.<ref>[http://webcache.googleusercontent.com/search?q=cache:GWzoIfATUFcJ:ftp://ftp.etsii.ull.es/pub/REDES2/doc/packet.txt googleusercontent.com/ull.es - PC/TCP Version 1.09 Packet Driver Specification, FTP Software, Inc.], 1989-09-14</ref> Packet drivers can implement many different network interfaces, including [[Ethernet]], [[Token ~~ring~~Ring]], [[RS-232]], [[ARCNET\|Arcnet]], and [[X.25]].<ref name="crpkt">{{cite web\|title=PC/TCP Packet Driver Specification\|url=http://www.crynwr.com/packet_driver.html}} 090430 crynwr.com</ref> == Functions ==
