Java + 3G USB dongle + SMS + javax.comm

This is 3rd post about SMS.

No time to rewrite the sms application on c#. Made the existing legacy java app robust. Let it survive for some time #zen

Here are some of the interesting facts –

  • We need to use good olden 32 bit JRE to continue to support javax.comm api
  • Win32com.dll doesn’t have an implementation for 64 bit

*Often, java doesn’t get response from serial port, it makes our situation pathetic in SLA. You don’t have control over it.

So far, I have used to devices.

  1. HSDPA 3g dongle from StarHub made by Huawei Device
  2. Wavecom GSM modem connected to usb via USB to Serial convertor cable.
