The AXEL tty Server
________________________________________________________________
54 TCP/IP AXEL Platine Terminal
This chapter describes the AXEL tty server and explains its installation and use.
It does not apply to terminals connected via a serial port, which were covered in
the previous chapter, Chapter 6.
7.1 - INTRODUCTION
The AXEL tty server associates a UNIX device (ptty) on the host with an
auxiliary port on the
AX3000
terminal. This enables data written to the UNIX
host device to be sent to the AX3000 port, and data received via the AX3000
port to be read through the UNIX host device.
For a UNIX host to act as a terminal server:
- The UNIX host must run the AXEL tty server daemon (
axttyd
). The
configuration file
axttyd
must contain a list of AX3000 ports and the
pttys associated with each.
- On the AX3000 the
tty
service must be selected. This is done through
the AX3000 Set-Up.
Note: this service can be associated with both serial and parallel ports.
When an AX3000, which has been configured with the tty server, is switched
on, an automatic connection to the required UNIX host is sought. If the AXEL
tty server on the UNIX host accepts this connection, the AX3000 port and the
ptty are linked. Thereafter any UNIX software can use the ptty to access the
AX3000 port.
