USDG Control mode
In controlling mode, the EKI serial device server presents a modem interface to the
attached serial device: it accepts AT-style modem commands to connect / disconnect
to other networking device.
If you want a serial device running application program to connect/disconnect to
different devices on request, this function is available through the USDG Control
mode.
Figure 4.7 USDG Control Mode
Please refer to the USDG TCP/UDP server operating mode to setup the Data Listen
Port, Command Listen Port, and Data Idle Timeout.
4.4.1
Hangup Character
The default character is “+”. After you have connected to another serial device an via
EKI device, you may need to disconnect, using the command “+++”. To do this, press
“+” three times and wait for the idle timeout <default value is 100ms>; the device will
disconnect. You can set “Guard Time” to define the idle time.
4.4.2
Guard Time
The default value is 1000 ms.
Example: <Guard Time>+++<Guard Time>
Control Mode is designed for use with legacy operating systems, such as MSDOS,
that do not support TCP/IP Ethernet. By connecting one of the EKI’s serial ports to
the MS-DOS computer’s serial port, it is possible to use legacy software originally
designed to transmit data via modem, but now transmitting data over the Ethernet.
Command
Function
ATD <IP address><TCP
port><CR>
Forms a TCP connection to the specified host.
Ex: ATD 192.0.55.22:5201
In above example, the EKI serial device server forms a
raw TCP connection to the networking device
(192.0.55.22). The TCP port is 5201.
ATA <CR>
Answering an incoming call
+++<CR>
Returns the user to the command prompt when entered
from the serial port during a remote host connection.
