The carrier COM port provides the following functionality:
H
If configured for ASCII, only one ASCII device may be used for the carrier. (If
two COM ports are configured for ASCII, neither will work.)
H If configured for Mgmt, each device in the carrier can support a Mgmt COM
port; however, each Mgmt COM port must be connected to a different subnet.
To facilitate IP data routing, the device with the closest link to the SNMP
manager or Telnet client should be configured as the IP Bus Master.
H
If configured for either ASCII or Mgmt, the carrier COM port may be
configured to control an external device (e.g., modem, x.25 PAD) through the
use of AT or user-specified commands.
