I have been used your second solution  (standalone service by java4less)
but i have very much problems to run and use it;

1) initializing modem by AT&T flow control command is very difficult because these commands are not easily known for any common kind of modems especially for our end users ;


2) sending and receiving fax by this package is possible for pure text and not for any documents types such pdf  or doc  extensions or images ;


please give me more explanations about this product or suggest me another standalone fax services in java.
