Line Protocols
1. Flow Control
The methods of flow control between the V.24 interface and the V.24 device
are configurable. There are two hardware methods and one software
method. These must be compatible with the method used by the attached
V.24 device.
The three methods are as follows:
•
RTS/CTS + DTR/DSR
•
RTS/CTS
•
CCITT (Xon/Xoff)
2. Connection Control
There are three configurable items:
•
BREAK CLEARS CALL ON/OFF
A break will cause the call to clear down.
•
DATA GUARDING TIME xx SECS
The call clears down after xx seconds without data being sent.
•
LOG OFF SIGN
The log off message sent to the attached V.24 device can be configured.
V.25bis Commands and Messages
The V.25bis commands are sent from the V.24 equipment and answered with a
corresponding message.
The ErgoLine D340 telephone discriminates between the operational state
command mode and the data transfer rate.
Initially the command mode is active, so commands can be given. After a
connection is established, the state changes to the data transfer state. In this
state no commands can be accepted.
The following settings are necessary for a successful operation.
•
Dial protocol V.25bis
•
Asynchronous mode
•
In the case that characters are double, or not seen at all on the V.24
equipment, select
local echo
on or off.
