Page 35: Operation
PORT MANAGER SWITCHES 6. Operation 6.1 Connecting and Disconecting Ports This section describes how to use ASCII commands to make and break connections between Port Manager Switch ports. Because the PM Switch converts data rates and other communications parameters, you can connect devices to the unit that use dissimilar data rates, parity, flow control, etc. - Page 36 CHAPTER 6: Operation To connect PM Switch ports, take these steps: 1. Access the PM Switch Command Mode. 2. Invoke the /C command to connect the desired ports. a) Resident Connection: To connect your resident port to another port, type “/C nn” (where nn is the number or name of the port you want to connect to), then press [Enter].
- Page 37 PORT MANAGER SWITCHES 6.1.2 D ISCONNECTING ORTS There are three different methods for disconnecting ports: the Resident Disconnection, the Third-Party Disconnection, and the No-Activity Timeout. Providing the timeout feature has been enabled, a No-Activity Timeout can be used to disconnect resident ports or Third-Party ports. NOTE When you use DTR flow control for a given port, the DTR signal will drop for approximately 250 ms after that port is disconnected from another.
-
Page 38: Defining Hunt Groups
CHAPTER 6: Operation c) The /D command line can specify port names instead of port numbers. However, port names are case-sensitive, so make sure you use the right case for each letter of the port name. 3. No-Activity Timeout: Providing that the Timeout Disconnection feature has been enabled for either connected port, the No-Activity Timeout can be used to automatically disconnect any two connected ports. - Page 39 PORT MANAGER SWITCHES 4. Repeat steps 2 and 3 above to assign similar or identical names to the other ports you wish to include in the hunt group. For example, a series of ports in a hunt group could be named “sequentially”—“PRINTER1”, “PRINTER2”, “PRINTER3”, etc.—or all ports in the group could be assigned the same name, such as “PRINTER”.

(that is, type “/E * [Enter]”). If your application requires more than 256 KB of buffer memory, call Black Box for technical support; they might be able to provide you with a special quote on PM Switches with 512-KB buffers. -
Page 41: Saving Configuration Parameters
PORT MANAGER SWITCHES 7. Saving Configuration Parameters After you have configured the Port Manager Switch to fit the requirements of your application, configuration parameters can be downloaded to your PC and saved as an ASCII text file. Later, if the configuration is accidentally altered or deleted, the file with the saved parameters can be uploaded to automatically reconfigure the PM Switch without the need to manually redefine each parameter. -
Page 42: Restoring Saved Parameters
CHAPTER 7: Saving Configuration Parameters 6. At the ProComm screen, type “/U” and press [Enter]. The PM Switch will send a series of command lines to the file specified in Step 5 above. Each line describes parameters for an individual port. a) The /U command must be invoked before ProComm’s download timeout is reached. -

The port’s DTR signal is wired through the modular adapters to PCs’ CTS (Clear to Send), DSR (Data Set Ready), and RLSD (Received Line Signal Detector)—also known as DCD (Data Carrier Detect)—input hardware leads.
- Page 51 PORT MANAGER SWITCHES Connect (/C) Establishes a bidirectional connection between two ports. There are two different types of PM Switch port connections: • Resident Connection: If the /C command specifies one port name or number, the PM Switch will connect your resident port with the specified port.
- Page 52 CHAPTER 8: Command Reference Guide Third-Party Disconnection (/D) When two ports are connected, the /D command can be invoked at a third port with “All” command capability in order to disconnect them. Note that the /D command cannot be used to disconnect your resident port. To disconnect your resident port, issue the Logoff Sequence (default = “[Enter]+++[Enter]”) or wait for the Timeout Period to elapse (if Timeout Disconnection is enabled).
- Page 53 PORT MANAGER SWITCHES Erase Buffer (/E) Erases data from the buffer for a specified port. Note that you cannot specify a port name; you must specify a port number or (to clear all port buffers) an asterisk. CAUTION! Buffered data which has been cleared by the /E command cannot be recovered.
- Page 54 CHAPTER 8: Command Reference Guide Initialize (/I) Tests the PM Switch’s internal memory and initializes the system with the default parameters specified by the SETUP switch configuration.
