5.5.2. Port Modes
The CMS-32 offers four different port operation modes; Any-to-
Any Mode, Passive Mode, Buffer Mode, and Modem Mode. The
Port Modes function as follows:
·Any-to-Any Mode: Allows communication between
connected ports. Any-to-Any Mode Ports can be connected
to other Any-to-Any Mode, Passive Mode, Buffer Mode, or
Modem Mode Ports by accessing Command Mode and
invoking the /C command (see Section 7.1.1.) The Any-to-
Any Mode is available to all ports.
·Passive Mode: Allows communication between connected
ports, but does not allow access to Command Mode. Passive
Mode Ports can be connected by accessing Command Mode
from a free Any-to-Any or Modem Mode port and invoking
the /C command (see Section 7.1.1.) The Passive Mode is
not available to Port 1, Port 2, or the Network Port.
·Buffer Mode: Allows collection and storage of data
received from connected devices. Collected data can be
retrieved by accessing Command Mode from a free
Any-to-Any or Modem Mode Port, and issuing the Connect
(/C) Command. Note that the Buffer Mode also allows
pass-through communication with the connected device.
When the Buffer Mode is selected for a given RS232 Port,
that port can also employ the optional Syslog feature and
SNMP Trap function. The Buffer Mode is not available to
Ports 1, Port 2, or the Network Port.
·Modem Mode: Allows communication between connected
ports and simplifies connection to an external modem. A
port configured for the Modem Mode can perform all
functions normally available in Any-to-Any Mode. The
Modem Mode also allows definition of a Hang-Up String,
Reset String, and Initialization String. Any CMS-32 RS232
port can be configured for the Modem Mode. The Modem
Mode is not available at the Network Port.
For more information on Port Modes, please refer to Section 7.
