Since HyperTerminal makes use of serial ports for data transfer, it can be used for loopback testing. It employs telnet or a standard RS-232 serial bus to connect with remote devices. A Loopback configuration is just what the name suggests: Among the signal lines of the RS-232, the Transmitted Data line (TxD) is looped back to the Received Data line (RxD) of a port at the same host. Loopback Test in HyperTerminal HyperTerminal permits your computer to act as a terminal to remotely connect with other systems. Between I have also changed this line of code nnect(“COM4”) but the problem seems to be pertaining to version of RxTx. The COM ports you connect are the typical PC implementation of the RS-232 serial interface. But unfortunate to see that I get the below error: (Earlier I was trying with comm.jar from sun’s website to run, later found to be obsolete and replaced with RxTx). I am trying to run this program on my 64 bit windows 7 machine, with Jdk 6, 64 bit version installed. Please post a comment if it doesn't work for you.Ģ0080829 – Add timeout, for case where you forget the loopback. I use Linux 2.6 SUSE SLED 10, Java 6, and RXTX 2.1.7 when testing this, and it's okay for me. The program has not tested the main issue yet (problem with data available event), but this basic test should be ok for any platform and any version of Java / RXTX. The program will simply send 1-character and wait to receive 1-character to be compared. Public void connect(String portName) throws IOException while ((elapsedTime < TIMEOUT_VALUE) & Take a metal paperclip or wire and cross pins 2 and 3. Import gnu.io.UnsupportedCommOperationException To check whether or not an RS-232 serial port is working, perform an RS-232 loopback test by doing the following: If your serial port is not female, convert it by taking a female/female cable or gender changer and plugging it into the serial port.
