<sect1>Joystick drivers<p>
|
||||
|
||||
Telemon 2.4 & 3.0 manages joysticks but it had been handled yet. This means that
|
||||
joysticks driver could be written easily.
|
||||
|
||||
Telemon 2.4 returns in keyboard buffer the direction of the joysticks. This means that
|
||||
if you get input from keyboard by conio cgetc function, you will get direction from joysticks.
|
||||
|
||||
Anyway, if you don't want to use ROM, you can use joysticks standard drivers in your code.
|
||||
|
||||
The standard driver manages two joysticks. Only one button is managed for theses joysticks.
|
||||
|
||||
Telestrat can handle one button for the left port, and three buttons for the right port (but this port was designed for a mouse).
|
||||
|
||||
If you find a Telestrat mouse (which almost impossible :), these driver will work too because there is some extra hardware in the mouse to send direction.
|
||||
|
||||
<sect1>Mouse drivers<p>
|
||||
|
||||
Telestrat manages also mouse, but it had been no handled yet in this version.
|
||||
Telestrat manages also mouse (Joystick port)
|
||||
Telestrat mouse is really difficult to find.
