I want to write application to send sms via COM port. Currently I have Windows, but then this application should works on Linux too. I found javax.comm library here: http://www.oracle.com/technetwork/java/index-jsp-141752.html but I don't know from where I can download jar file ? Then I found RXTX library but I don't if it is good ?
Thanks
I'd suggest you to use SMSJ. It has several implementations. One is "local": it wraps RXTX library providing higher level well designed API. Others use well-known web services that send SMSs.
