'''PC/TCP Packet Driver''' is an [[Application programming interface|API]] created in 1986 by [[FTP Software]] for [[network card|network cards]]s under [[DOS]]. It uses an [[INT (x86 instruction)|x86 interrupt number]] (INT) between 60h and 80h, most commonly 60h. The exact interrupt is detected at runtime.

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}}

Packet drivers can implement many different network interfaces, including [[Ethernet]], [[Token ring]], [[RS-232]], [[ARCNET|Arcnet]], and [[X.25]]. <ref name="crynwr_com-packet_driver">{{cite web|title=PC/TCP Packet Driver Specification|url=http://www.crynwr.com/packet_driver.html}} 090430 crynwr.com</ref>
