串行埠

Macintosh 曾經常見嘅 RS-422 串行埠(最右面圓形嗰兩個)
其他個人電腦曾經常見嘅9針 RS-232 串行埠

串行埠[1]英文serial port)係一類電腦硬體介面,通訊埠一種,用lei4電腦週邊設備,而通訊嘅方法就係串行通訊,亦即逐個位元串行傳輸;喺 Mac 機傳統上係指 RS-422,其他類型嘅個人電腦就通常係指 RS-232,後者早期係25針,後來通常係9針。

USB 埠技術上其實亦都係一種串行埠(USB 嘅 S 指 「串行」),不過講串行埠通常唔會指 USB。

gaa1嘅個人電腦已唔會有串行埠,但係因為有啲科學儀器仍然用呢種介面,市面上可以買到一啲串行插頭轉 USB 插頭嘅適配器。
