'''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 [[FreeDOS]], [[DR-DOS]], [[MS-DOS]], etc. It uses the [[INT (x86 instruction)|x86 interrupt number]] (INT) between 0x6060h .. 0x8080h. The exact number is detected at run-time. But it's usually 0x6060h.

An application scans through the handlers for vectors 0x6060h through 0x8080h until it finds one with the text string "PKT DRVR" in the 12 bytes immediately following the entry point.{{clarify|post-text= - techspeak, relevance?}}

The driver can handle [[Ethernet]], [[Token ring]], [[RS-232]], [[ARCNET|Arcnet]], [[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>
