Enterasys Networks Wireless Ethernet Adapter I manual Passthrough2

Using the Terminal Configurator

CTS and DSR are output lines. When set to “negate” or “assert,” they will output a continuous digital value. The value “negate” outputs a logic 1, or “mark” which is electrically negative. This is also the state seen on an RS-232 connector when the cable is unplugged. The value “assert” outputs a logic 0, or “space” which is electrically positive. When set to “passthrough,” CTS will output the value that the remote Ethernet Adapter is receiving on its RTS line, and DSR will output the remote DTR value. The source of these remote signals depends on the remote Ethernet Adapter’s “socket” setting in this section.

∙resend interval. Ordinarily, the digital input lines are transmitted whenever they change. In some cases (such as when the remote unit is turned off and then on so that it forgets the previous output states), this is insufficient. Setting this resend interval value to a non-zero number causes the state of the input lines to be re-transmitted in a regular interval. The value of this setting is in seconds.

∙socket. This entry specifies a network connection to use to send the RTS and DTR input states to a remote Ethernet Adapter. The value of this setting must be the name of a section that describes the network connection to use. Also, the connection must use the RMP protocol. This is typically set to the rmpbind section.

[passthrough]

The following section specifies the operating parameters for the passthrough protocol. Currently, the only entry is socket.

socket. The section it specifies contains the values necessary to “bind a socket,” in other words, what needs to be known to create a network connection. For example, this value by default is rmpbind. The connection used by passthrough mode will create a socket that uses the values in the [rmpbind] section further down in the file to create the network connection.

[passthrough2]

With passthrough2, there are two sockets: one for incoming data (listen), and one for outgoing data (connect). Both of these sockets must use the TCP/IP protocol.

∙listen. As in the socket key for the [passthrough] section above, the value of this entry represents the name of another section that defines a network connection. This value by default is tcpbind1a. A later section in this file is also named [tcpbind1a]. Thus, the connection used by passthrough mode will create a socket that uses the values in the [tcpbind1a] section to create the network connection.

∙connect. The value of this entry points to a network connection definition that initiates the connection instead of listening for it. The default for this setting is tcpbind1b.
