RADIOTELEX

3 Installation and configuration

TELEX TTY setup

During communication the terminal is not necessarily the active window. The
TTY setup specifies how many minutes it is allowed not to be in the terminal
before the communication is broken.

This function only applies to conversation, and only when Radiotelex is the
master.

Values of zero disable the time outs.

TELEX retry setup

There is no guarantee that MF/HF transmissions are successful every time.
The ‘hit rate’ is not like e.g. Inmarsat-C communication. That is the reason for
the retry concept: If a transmission is not successful, it is stored in a retry
schedule, and retransmission can be attempted at a later time.

In the TELEX retry setup it can be specified how many times retransmission
is to be attempted and how many minutes there are to be between each
attempt. Furthermore, different values can be specified for ship calls and
coast station calls.

Values of zero disable the retry schedule.

Note that if a transmission is broken by using 

F9

 Break, the transmission is

deleted from the retry schedule automatically.

Transmissions in the retry schedule can be viewed or deleted in the transmis-
sion table available by pressing 

F3

 TX in the terminal and then 

F5

 TX Table.

TELEX secret reception setup

Secret reception may be initiated upon the reception of a configurable
sequence of characters. The secrecy continues until the connection is broken
or, if specified, either of two programmable sequences of characters are
received.

During secret reception nothing is printed. Also, the keyboard cannot be used
to send anything to the connected subscriber.

Secret reception is logged in a special password protected file queue
irrespective of the configuration of the normal log.
