TCP/IP AX3000 User's Manual  79 
A VNC terminal without Login is defined by: 
- its display number: this is the VNC session TCP port (1=5901, 2=5902...), 
- its resolution:800x600, 1024x768 or 1280x1024, 
- its number of supported colour bits: 8 bits/pixel (256 colours) or 16 
bits/pixel (65535 colours, only on models 75/75E). 
- the dedicated application (absolute pathname and parameters). 
Notes: 
- The Xvnc server and application are run by the RunScriptVNC script 
which is automatically created by axvnc. The RunScriptVNC scripts are 
launched through /etc/inittab. 
- If an entry in the display table is 'busy', it means the VNC terminal WITH 
login is assigned to this port. 
5.3 - CONTROLLING PRINTERS 
Three auxiliary ports are provided by the AX3000 (2 serial and 1 parallel). 
These ports are independently controlled so up to three 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, NT, 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.
