The AXEL Proprietary Network Servers
________________________________________________________________
62 TCP/IP AXEL Platine Terminal
This chapter introduces the TCP/IP AX3000 print and tty servers.
This chapter is dedicated to the three AXEL proprietary network servers. These
servers are used to control AX3000's printers. They are written in the C
language and may be compiled and linked (for whichever UNIX System is
being used) if the binary executable files are not available.
Note: refer to the Chapter 5 to install the standard UNIX print servers: lpd and
rcmd.
8.1 - INTRODUCTION
8.1.1 - Overview
Three auxiliary ports are available on TCP/IP AX3000 models:
- 2 serial ports,
- 1 parallel port.
These ports can be managed either by escape sequences (as on any serial
terminal) or by the AXEL print and tty servers.
The AX3000 embedded TCP/IP servers associate a UNIX device with one of
the three auxiliary ports on the Platine terminal. The peripheral attached to the
Platine terminal is then accessed through this UNIX device. When using
auxiliary peripherals, the AX3000 will still maintain a normal screen display
capability.
For example, this feature allows a printer, connected to any of the auxiliary
ports, to be treated as a system printer. This printer can be used by any
