I understand that we can use SMS Sender in command line mode. But i been getting this error same as this article http://www.oreillynet.com/pub/a/wireless/2003/10/10/sms.html
The smssender.exe will use the last device that was successfully used to send messages in the Windows version of SMS Sender. But I tried it many times, and smssender.exe always complains that no last device was used.
Anyone have any idea about this?
