问题：
有时候不能发送短信？出现异常：
Example: Send message from a serial gsm modem.

or other supported gateways.

at org.smslib.modem.AModemDriver.connect(AModemDriver.java:149)
at org.smslib.modem.ModemGateway.startGateway(ModemGateway.java:111)
at org.smslib.Service$1Starter.run(Service.java:227)

sim卡是用的联通的，环境正确了 ，有时候能发送，速度也还比较快。

程序是通过读取数据去去取得短信，然后调用发送方法！
