Build from Source

Prerequisites

You will need a working, recent (v1.22 or later) Go compiler. The first time you build or install DasherG it might pull in the toolkit dependencies - this will take a little while. Subsequent builds should be very quick.

Build

go build

or, if you prefer

go install

Running DasherG

From the build or install directory simply type

./DasherG

Optionally, you may add the -host=host:port argument to connect to a running host via telnet. Eg.

./DasherG -host=localhost:23

For a full list of all available DasherG options type

./DasherG -h

Function and Special Keys

You may have to use the keys simulated on the toolbar in DasherG as your OS might interfere with the physical function keys on your keyboard. The Shift and Control keys can be used in conjunction with the simulated F-keys just like a real Dasher.

The "Brk" button sends a Command-Break signal to the host when connected via the serial interface.

"Hold" and "Local Print" work as you would expect, although the print actually goes to a user-specified image (PNG) file.

Bell Sound

For the system bell to operate, DasherG must have been started from a terminal which supports the bell.
