Solution:

In the Data mode communication of the ADAM-4577/79, device can transfer the TCP/IP data to serial. If user need to change the serial parameters in the run-time of the application, please follow the below steps: 1. Use Socket program or application to connect the TCP control port, normally it is 5200. 2. Send the command string "AT$PS=1" or "AT$PS=2" to select the target serial port. 3. Wait for the reply "\n\rOK\n\r" from the ADAM-4579 4. Send the command string "AT$PCF=dddd, [N | O | E | S | M], [5 | 6 | 7 | 8], [1 | 1.5 | 2], where dddd is baud rate, [N | O ...] is parity bit, [5 | 6 ...] is the data bit [1 | 1.5 ...] is stop bit. Please exactly conform to the sequence and format of command. 5. Wati the reply "\n\rOK\n\r" from the ADAM-4579. Please note this is a run-time change and the settings will be eliminated while the device reset. That means the setting will be back to refer to the setting done by utility. And this run-time change will not be shown on the relative utility.
