- ASCII: keyboard events are the same than the top row keys (above QWERTY). With
this mode an application can't distinguish is the pressed key belong or not to the
numpad. This mode may be required for some JAVE-based applications.
- . (numpad) : the two available values are the dot (.) and the comma (,).
- <Scroll Lock> & <Pause>: enable or disable these two keys
- <Alt Gr> Mode: this parameter sets the type of keyboard event sent when pressing <Alt Gr>
(located at the right of the space bar:
- Standard: the keyboard event is AltGr.
- Ctrl+Alt: the keyboard events are <Ctrl> and <Alt> (left of the space bar).
- Local Mouse Cursor : if 'no', the mouse cursor is fully handled by the VNC server. If 'yes',
the behavior depends on the VNC server version:
- Xvnc V3: as above the mouse cursor is handled by Xvnc. In addition the local mouse
cursor location is indicated by a little square pointer (2x2 pixels). This can be useful
when the local mouse cursor location is different from the VNC cursor location (for
example when the Unix/Linux server or the network is overloaded).
- Xvnc V4: the mouse cursor is handled by the AX3000. With a low-bandwidth, this
allows the mouse cursor to be more reactive.
- Emulate a 3-button Mouse : if 'yes', the mouse middle button is emulated by clicking both
left and right buttons.
- Mouse Sensitivity : This setting varies the sample rate of the mouse. If the sensitivity is
increased the mouse movement will be more fluid, but also network activity is increased.
8.3 - CONTROLLING PRINTERS
Auxiliary ports (2 serial and 1 parallel), logical USB ports and network printer ports are provided by
the AX3000. These ports are independently controlled so multiple printers can be attached to the
AX3000.
A printer is generally controlled by a network service:
- tty protocol : this is an Axel proprietary protocol. A printer controlled by the tty protocol is
seen as a local printer.
- LPD protocol : this service (RFCs 1048 and related) is provided as a standard feature by
major operating systems (Unix/Linux, Windows, etc.). The main benefit of this protocol is an
LPD printer can be shared by different operating systems.
- rsh command : this command allows the contents of a file to be redirected over the network.
In addition, a printer can also be controlled in "transparent mode" (by embedded escape
sequences, like a printer attached to a serial terminal).
The following covers the tty protocol, the rsh command and the transparent mode. For more
information about LPD printers, refer to Appendix A.3.
8.3.1 - The tty Protocol
The tty server is an Axel proprietary protocol. An additional piece of software is needed (see
Chapter 8.4).
The Unix/Linux host must run the AXEL tty server daemon (
axttyd
). The configuration file
axttyd
must contain a list of AX3000 auxiliary ports and the pttys associated with each.
