I am developing an sms server how can know the com port automatical which the modem is connected without telling the user to go to window device manager to check the com port then put the com port manully

推荐答案

我担心您将不得不穿过com端口，并对其进行轮询以查看它是哪一个.调制解调器不是即插即用的，因此不与它们交谈就无法知道.

I fear you''ll have to walk the com ports, and poll them to see which one it is. Modems are not plug ''n play, so there''s no way of knowing without talking to them.
