发送命令到与gsm调制解调器与Java

我想做一个程序发送短信。我编写了程序，但没有成功发送消息。我的程序向我的计算机的端口COM发送一个At命令，但是我没有收到我的GSM调制解调器的响应。我正在使用COM终端（Temp pro ...）使用at命令发送短信，并且我可以发送短信。所以我不知道为什么这个程序不能发送短信。发送命令到与gsm调制解调器与Java

而不是使用'调用println（ “ERR3”）的'放一个'e.printStackTrace（）'在'catch'条款。这可能更好地解释什么是例外。在所有'catch'子句中这样做，[编辑]你的问题并将堆栈跟踪添加到它。记住要正确格式化它（不使用反引号，而是使用'{}'按钮）。 – RealSkeptic

好的我做的程序，我可以发送短信。我使用CTRL + Z和Enter，这是一个问题。：d
