119 Joystick Event Reporting
122 In this mode, the ikbd generates a record whenever the joystick position is
123 changed (i.e. for each opening or closing of a joystick switch or trigger).
125 The joystick event record is two bytes of the form::
127     %1111111x           ; Joystick event marker
128                         ; where x is Joystick 0 or 1
132 Joystick Interrogation
135 The current state of the joystick ports may be interrogated at any time in
136 this mode by sending an 'Interrogate Joystick' command to the ikbd.
138 The ikbd response to joystick interrogation is a three byte report of the form::
140     0xFD                ; joystick report header
141     %x000yyyy           ; Joystick 0
142     %x000yyyy           ; Joystick 1
146 Joystick Monitoring
150 time to reporting the state of the joystick ports at a user specifiable rate.
159 this mode the ikbd monitors the state of the Joystick 1 fire button at the
166 Joystick Key Code Mode
169 The ikbd may be commanded to translate the use of either joystick into the
171 velocity joystick cursor.
172 Joystick events produce the make code, immediately followed by the break code
202 either axis and the Y=0 origin at the top of the screen, and joystick event
203 reporting mode for joystick 1, with both buttons being logically assigned to
204 the mouse. After any joystick command, the ikbd assumes that joysticks are

435 joystick events are also queued.
448 When the ikbd is in either the JOYSTICK MONITORING mode or the FIRE BUTTON
452 SET JOYSTICK EVENT REPORTING
459 Enter JOYSTICK EVENT REPORTING mode (DEFAULT). Each opening or closure of a
460 joystick switch or trigger causes a joystick event record to be generated.
462 SET JOYSTICK INTERROGATION MODE
469 Disables JOYSTICK EVENT REPORTING. Host must send individual JOYSTICK
470 INTERROGATE commands to sense joystick state.
472 JOYSTICK INTERROGATE

541 In this mode, joystick 0 is scanned in a way that simulates cursor keystrokes.
558 Disable the generation of any joystick events (and scanning may be internally
559 disabled). Any valid joystick mode command resumes joystick monitoring. (The
560 joystick mode commands are SET JOYSTICK EVENT REPORTING, SET JOYSTICK
561 INTERROGATION MODE, SET JOYSTICK MONITORING, SET FIRE BUTTON MONITORING, and
562 SET JOYSTICK KEYCODE MODE.)
