connection time out is not reached. Once internal timeout reached (the
internal timeout of the modem is fixed to 5 minutes), the connection is
released from the modem side and the modem is ready to receive a new
incoming set-up connection.
Transmission Mode
The data transmission is performed through the wireless LAN using TCP-IP
protocol. The modem is ready to send or receive data when it leaves its set-
up phase.
AFTER POWER-UP, NO CHARACTERS MUST BE TRANSMITTED ON
THE SERIAL LINK DURING A MINIMUM DELAY OF 5 SECONDS TO
ENSURE PROPER BOOT OPERATION OF THE MODEM.
Connection of the modem on a remote server
The modem acts as a client. It is ready to establish a remote connection after
a delay of 5 seconds after a power-up or a set-up configuration phase.
The following behaviour can only be expected if the recommended settings
have been set on the modem (see chapter SET UP). The TCP communication
is established by the modem when it receives any character from its serial
link. On the first character reception, the modem tries to connect on the
remote server specified by the remote IP and the remote port and data are
transmitted. If the remote server cannot be reached, data sent on the serial
link are kept in the internal modem buffer (in the limit of its size) and are
sent when the modem finally succeeded in connecting to the host.
The connection remains active while the modem is powered. If the host side
disconnects, the modem re-attempts to connect until the connection to the
host is successful.
Connection of a client on the modem
The modem acts as a server while it is powered. The modem is ready to
accept an incoming connection after a delay of 8 seconds after power-up or a
set-up configuration phase. There is no password to connect to the modem.
The connection is never closed by the modem.
