'''PC/TCP Packet Driver''' is an [[Application programming interface|API]] created in 1986 by [[FTP Software]] for [[network card|network cards]]s under [[x86]]-[[Disk Operating System|DOS]]es like [[MS-DOS]], [[DR-DOS]], [[FreeDOS]], etc. It uses thean [[INT (x86 instruction)|x86 interrupt number]] (INT) between 60h .. 80h, most commonly 60h. The exact numberinterrupt is detected at run-timeruntime. But it's usually 60h.

An application scans through the handlers for vectors 60h through 80h until it finds one with the text string "PKT DRVR" in the 12 bytes immediately following the entry point.{{clarify|post-text= - techspeak, relevance?|date=August 2012}}
