notebook 沒有com port 怎樣連接 cisco switch

你試一下用USB to RS232的轉換線
或者PCMCIA to RS232吧

基本上我用來連接Barcode槍及收銀機都可以的
朋友公司也是用USB to RS232轉換線來接CISCO Switch
但不是每一個牌子的轉換線也穩定
要買好一點的

參巧一下以下文章

Easiest way is to get a RJ45 to RS232 cable or converter. Most cisco routers come with one of this cable these days. I have been using it (from the cisco switch box) since 2002. For more information about RJ45 to RS232, see the followings:
