The carrier COM port provides the following functionality:
„
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.)
„
If configured for Mgmt, each device in the carrier can support an 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.
„
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.
The set of valid characters for control of the carrier external COM port device is as
follows:
„
The numbers: 0–9
„
The lowercase letters: a–z
„
The uppercase letters: A–Z
„
The space (“ ”) character
„
The ASCII symbols (in ascending order, based on the ASCII code)
„
The End Of Line (EOL) symbol:
←
„
The caret (“^”) control character is used to select non-printable ASCII
characters. The caret “^” must be followed by one character which together
form the control sequence.
Table 4-2, Control Sequence , defines all of the
available control sequences.
