'''PC/TCP Packet Driver''' is an [[Application programming interface|API]] created in 1986 by [[FTP Software]] for [[network card]]s under [[x86]]-[[Disk Operating System|DOS]]es like [[FreeDOSMS-DOS]], [[DR-DOS]], [[MS-DOSFreeDOS]], etc. It uses the [[INT (x86 instruction)|x86 interrupt number]] (INT) between 60h .. 80h. The exact number is detected at run-time. 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?}}
