Вобщем, в итоге для работы с COM портом получилась такая штука: | Код |
/**
* Class for working with RS232 serial ports.
* Uses ActiveX, i.e. MSIE only compatible. MSCOMM32.OCX properly installed and registered is also needed.
*
* Small using example:
* <code>
* var comm = null;
* var request = 'ATX\r';
* var answer = '';
*
* // Pseudo-obj creation
* new COMPort(1, '9600', 'N', '8', '1', 100);
*
* // Needed obj creation
* comm = new COMPort(1, '9600', 'N', '8', '1', 100);
*
* // Obj initialization
* if (!comm.init()) alert(comm.Errors[comm.lastErrorIndex]);
*
* // Opening port
* if (!comm.open()) alert(comm.Errors[comm.lastErrorIndex]);
*
* // Sending data in port
* if (!comm.send(msg)) alert(comm.Errors[comm.lastErrorIndex]);
*
* // Receiving data
* if (!(answer = comm.receive())) alert(comm.Errors[comm.lastErrorIndex]);
* else alert('You have received: ' + answer);
*
* // Closing port. Don't forget abuot it! No other application can use port if it is not closed.

Если не указывать на каком порту модем, может быть найдет его сама, а может и нет  Не проверял. P.S. Предложения и замечания тоже приветствуются... --------------------
