DTRWait

Note: DTRWait is not available in RS-485 mode.

Spurious characters from the modem may be interpreted as a user login, which could cause the port to be unavailable for connections. To avoid this behavior, the MSS uses the Data Transmit Ready (DTR) output line to signal the serial device that a connection is possible or acceptable.

Normally DTR will be asserted when the port is idle, which allows devices to answer an incoming connection; many devices will not do so unless DTR is asserted. The DTRWait feature keeps the MSS from asserting DTR until the port is actually in use (whether due to a login or a network connection). To control DTRWait, use the Change Port DTRWait command.

The MSS will generally assert DTR when a connection begins and de-assert DTR when the connection ends.

Logouts

In addition to DSRLogouts, the port can be manually logged out, or it can be configured to automatically log out when it has been inactive for a pre-determined length of time. To manually log out of the MSS, type Logout at the Local> prompt, or press Ctrl-D.

Local>> LOGOUT

To log out the port after a specified period of inactivity, use the Change Port Inactive Logout command. This command works in conjunction with Change Server Inactive Timer, which defines how long a port must remain idle before it is automatically logged out.

For example, to make the MSS log out the port after two minutes of inactivity, use the following commands. The inactivity logout timer period can be specified in seconds (s) or minutes (m). For example, changing 1m in the example to 60s produces the same results.
