TCP/IP AXEL Platine Terminal 3
The host uses a software ‘driver' to manage a serial I/O (input/output) controller
(for example COM1 on the serial I/O board).
The terminal has a dedicated circuit associated with each serial port, which
transmits and receives characters over the asynchronous line.
1.1.2 - Network Connection
An AXEL TCP/IP Platine terminal operates quite differently from a conventional
terminal.
The following figure illustrates the Ethernet data communication process
between an AXEL TCP/IP Platine terminal and a UNIX host:
On the host a network 'package' is used to manage the Ethernet controller with
Telnet (host) and TCP/IP protocols. Each connected terminal is addressed via
a pseudo-terminal (ptty).
Each Axel terminal has an embedded Ethernet controller with built-in Telnet
(client) and TCP/IP protocols.
