The AXEL tty Server
________________________________________________________________
TCP/IP AXEL Platine Terminal 57
7.2.2 - TCP/IP Set-Up
Enter the AX3000 TCP/IP Set-Up (<Ctrl><Alt><
>).
Select the vertical menu [Terminal] then select the item for the relevant
input/output port: Add AUX1 or Add AUX2 or Add Parallel. Enter the following
parameters:
- Hostname enter the name of a host (which must have been
previously declared in the 'Network' menu, through
the 'Add Host' option - refer to Section 2.2.3).
- Auto Reconnect 'y': a new connection is automatically established
after a disconnection.
'n': if a connection is closed, the AX3000 must be
power-cycled to establish a new connection.
Exit Set-Up ([Session]
[Quit]).
Note: during the test period, do not use the auto-reconnection option.
7.2.3 - Open a Connection...
A tty connection will be established:
- when the AX3000 is powered on,
- after a disconnection, if the auto-reconnection option is used (a
reconnection is performed after 12 seconds).
On the UNIX side, this connection is performed on TCP Port 2048. The AXEL
tty server (
axttyd
) listens on this TCP port.
When the connection is established, the AX3000 sends a character string
containing the AX3000 IP address and the name of the AX3000 auxiliary port
(separated by the NULL character). With this information, the AXEL tty server
can identify the pair 'AX3000/auxiliary port'. If this pair is not an authorised
association (see next chapter), the AXEL tty server drops the connection.
Otherwise a link is made between the ptty and the AX3000 port.
