Gnublin on Windows

Download and install drivers

To get a connection to GNUBLIN you will need two things:

  • Virtual COM port driver for the USB-to-serial converter CP2102 of GNBULIN
  • Terminal program

Get the virtual COM port driver for the USB-to-serial via windows update or here:

XP/Server 2003/Vista/7/8 (v6.6.1): http://www.silabs.com/Support%20Documents/Software/CP210x_VCP_Windows.zip

Windows 2000 (v6.3a): http://www.silabs.com/Support%20Documents/Software/CP210x_VCP_Win2K.exe

Installation takes place as usual in Windows (download and install). After the installation GNUBLIN should be recognized by the host PC.

A good terminal program under windows is Tera Term: http://ttssh2.sourceforge.jp.

The following screenshot shows the console of Tera Term:


On the left bottom you can see the icon of Tera Term.

Tera Term is only available for Windows. From the perspective of the license, you can use it for free and carefree as it is subject to the BSD license.

Those looking for a similarly convenient program under Linux, I recommend ckermit.

You can also see, that Tera Term is able to use ssh and telnet,too.

The following screenshot is showing you the correct settings of the COM port for a connection to GNUBLIN. On windows, the serial interfaces are named "COMx" (x stands for a number).


Transmitting data

Tera Term can handle datatransfer with different protocols over the serial line. GNUBLIN can handle ZMODEM (lsz for sending files to the host, lrz for receiving data from host).

In order to receive data (from GNUBLIN) type following command:

lsz <File>

and add the following line to the file TERATERM.INI :


The Tera Term button "About" opens the following window:
