Configuring Incoming-Only Modem Connections

This section describes how to configure incoming-only modem connections, that is, connections that are initiated by a device across the telephone network.

Starting Point

This procedure assumes that you

• Know the operating parameters required by the modem. If you do not, see the modem documentation.
• Have or will correctly cable the connection between the Digi device's serial ports and modems. 
• Logged in as the administrator

Procedure

1. Supply a set ports command that specifies the following:
   • The serial port to which this command applies (on the range field)
   • dev=min
2. Supply a set line command that specifies the following:
• The serial port to which this command applies (on the range field)
• The line speed of the connection between the modem and the serial port (on the baud field)
3. Supply a set flow command that defines the flow control scheme required by the modem.

Example

In this example, ports 4 and 5 are set up for incoming modem connections using RTS/CTS flow control.

set ports range=4-5 dev=min
set line range=4-5 baud=115200
set flow range=4-5 ixon=off ixoff=off cts=on rts=on
