Chapter 5 – Network-to-Serial Connectivity Using Dialout

Command Line Interface and Application Examples for Multi-Tech Systems, Inc. IP Modules (S000368F) 73

Scenario 3 – Auto Dialout in RAW Mode

In this scenario, the Auto-Dialout session in RAW mode is opened using a RAW-TCP client.

Prerequisites

RAW mode (Global and each port) MUST BE ENABLED using the Optional Configuration Commands.

The Auto Dialout session can be opened by a RAW-TCP client by specifying the auto-dialout configured port. Once

the session is opened successfully, there can be two-way traffic between the Telnet session and the remote serial

device.

Important – You cannot switch between the Command Prompt and the Dialout session in RAW-mode.

Auto Dialout Feature in RAW Mode

Commands to Setup Auto Dial-out in RAW-Mode for the IP Module

# set ip telnet auto-dialout enable

# set ip telnet raw-mode enable

# set serial s0 stop-bits 1

# set serial s0 baud-rate 115200

# set serial s0 data-bits 8

# set serial s0 parity none

# set serial s0 flow-control rts-cts

# set serial s0 auto-dialout enable

# set serial s0 raw-dialout enable

# set serial s0 auto-dialout-port 5000

# set serial s0 auto-dialout-protocol telnet

# set serial s1 stop-bits 1

# set serial s1 baud-rate 115200

# set serial s1 data-bits 8

# set serial s1 parity none

# set serial s1 flow-control rts-cts

# set serial s1 connect-type modem

# set serial s1 modem dial-number 123

# set serial s1 modem dialing-trig-mode none (See Chapter 4 - Scenario Setup Prerequisites)

# set ppp ppp0 ipcp-mode client-only

# set ppp ppp0 username "IP module"

# set ppp ppp0 password "IP module"

# save

Notes

• Once the physical link is up and PPP interface has acquired an IP address the

• Wireless IP modem is ready to accept Auto dialout connection.

• Use a Telnet client. Connect to 202.54.39.95 on port 5000 (RAW TCP socket). This establishes a Telnet

auto-dial-out session in RAWMODE with the IP module, thereby opening the serial port for use.

• Closing the Telnet client closes the serial port in use.

• You cannot open more than one dialout session to the same port.

• When the Dialout session authentication is enabled as specified in the Optional Configuration Commands,

the session prompts for a user name and password before opening the session successfully.

• The serial port is opened with the current serial configuration.
