Inkcazo: I- RS-232 iyimilinganiselo yokunxibelelana kwee-telecommunications yokudibanisa ezinye iintlobo zezixhobo zombane. Kwiinkcukacha zekhomputha , ii-RS-232 zazisetyenziswa ngokuqhelekileyo ukudibanisa iimodem kwiichwepheli ezilandelelanayo zeekhompyutha. Izixhobo ezibizwa ngokuba yi- null modem zingaphinde zixhunyaniswe ngqo phakathi kwee-RS-232 kumachwepthi amabini kwiikhomputha zombini ukwenzela uqhagamshelwano olulula olufanelekileyo lokudlulisa iifayile.
Namhlanje, ezininzi iindlela zokusebenzisa i-RS-232 kwi-computer yonxibelelwano ziye zatshintshwa ngubuchwepheshe be- USB . Ezinye iikhomputer kunye neenethwekhi zineenethiwekhi zineenqwelomoya ze-RS-232 zokuxhasa ukuxhomekeka kweemodem. I-RS-232 iphinda isetyenziswe kwezinye izixhobo zoshishino, kubandakanywa intambo entsha yefiber optic kunye nokuphunyezwa kwentambo.
Eyaziwa ngokuba njenge: I- Standard Standard 232
