I m working on communicating with modem thru serial port using javax.comm
package.

I m able to dial through my modem connect to another modem login and
successfully disconnect. but the problem is when i pass more than one phone
no(modem) to my program it dials the first no login in that disconnects
also(maybe) but then it give me a string 'OK ' and the program is hang up. I
don't know where is the loop hole.

If any one of you have worked on this before, I request their help. Plz help me
to find the bug
