If set, SoftwareSerial treats a LOW (0 volts on the pin, normally) on the Rx pin as a 1-bit (the idle state) and a HIGH (5 volts on the pin, normally) as a 0. Once serial ports identified you can configure Linux box using various utilities: wvidial or other GUI dial up networking program – a PPP dialer with built-in intelligence. First use the VirtualBox option to enable a serial port to send output through Host pipe to a raw file. The print server works fine as it is being used from other computers on my home network. By default, gdbserver keeps the listening TCP port open, so that additional connections are possible. This is a guide to setting up a power monitoring system using Brultech GEM, ECM-1240, or ECM-1220 devices. 1:3000, or the real host ip address 192. [yourSerialPortName] [yourBaudRate] You will enter your specific information to replace what is between the [ ] in this command. In computer networking, and more definitely in software terms, a port is a logical entity which acts as a endpoint of communication to identify a given application or process on an Linux operating system. Both of the above have much more features than this purpose, but if you've set these up, you now have an environment against which you can test your interface. To specify a port that is either source or destination: tcpdump port 8080. Though [David] could have easily used USB OTG for this project.
