If so, configure HyperTerminal for this device.

It is possible that COM1 and COM2 are already present and that the adapter will appear as a new COM port, COM3 (or above) when connected and the driver is loaded.

The serial adapter will appear as a COM device and can be operated through HyperTerminal, which is included in a standard Windows install.

ĭownload and install the driver using the instructions. If you are running minicom on Fedora and get "Device /dev/ttyUSB0 lock failed: Operation not permitted" errors, re-create the /var/lock/lockdev directory - more info at. Then connect the adapter and run "minicom" again. Run "minicom -s" to configure it with the settings suggested above. minicom is also packaged in major Linux distributions. The by-path aliases are quite long, but are unique by USB socket.Īn older option is to use minicom, however this adds complex configuration and menus. Look for device aliases at /dev/serial/by-path or /dev/serial/by-id. when you have many serial adapters, it can be difficult to figure out which one is which.Either turn off power management, or prevent it from interfering by prefixing the command with olpc-nosleep, or just restart screen if you can afford to lose output. if you use an XO as the host, with power management enabled, the /dev/ttyUSB0 device may disappear as a result of suspend.some hosts, including XOs with OLPC OS, may have trouble using a serial adapter, see more detail.screen is configured slightly differently across our builds with respect to the terminate key, ctrl+a \ works on 11.2.0, but not 10.1.3, but ctrl+a K works with both.if you use an XO as the host, screen may be missing because it is not included in our builds, you may install it using yum.use ctrl+a K to close the screen "window" for the connection and terminate screen.Linux can be configured to respond to a BREAK. Open Firmware responds to a BREAK by interrupting the currently executing code. use ctrl+a ctrl+d to detach from the screen, then to reattach: screen -r,.incoming serial console data is displayed,.what you type is sent to the serial console,.replace /dev/ttyUSB0 with whatever device is appropriate,.the -L flag creates a log file, such as screenlog.0,.To connect to the serial console, use screen: Plug in the adapter and the kernel will create a device /dev/ttyUSB0, or later. So in RS232 modes hardware flow control must be disabled. The RS232 flow control lines on the DB9 were left unconnected and can float such that the flow control is asserted. Therefore the hardware flow control setting does not matter. In the USB modes the hardware flow control pins are wired so that they are de-asserted.The serial console can then be operated through any standard terminal application using the following settings:

The serial adapter contains an FT232R chip made by FTDI, and there are drivers for all major operating systems. For example, this adapter is enclosed in 20mm diameter yellow, and 13mm diameter clear, so that the indicators D2 and D1 can be seen. For regular use in a crowded workspace, enclose the adapter in heatshrink. Take care not to allow contact between the serial adapter circuit board and metal objects.
