5.2 Other Port Characteristics
5.2.1 DTRwait
The DTRwait flag governs whether a port provides DTR when idle. [[[Normally DTR is always asserted.
In general, this allows modems to answer an incoming call, as many modems will not answer a call unless
DTR is asserted.]]] If you enable DTRWait, the Server will deassert DTR until the port receives a
connection request. When such a connection begins, the Server will assert DTR; when the connection is
closed, DTR will be de-asserted.
Figure 5-10: Enabling Dtrwait
5.2.2 Port Names
The default name for each port is Port_n, where n denotes the port number. To assign a new name to a port,
use the Set/Define Port Name command.
Figure 5-11: Assigning Port Name
A default username can also be specified for a port using the Set/Define Port Username command. When
the username is specified with the this command, users will not be prompted for a username upon login.
Figure 5-12 displays an example.

5.3 Security
5.3.1 Password Restrictions
Users can be required to enter the Server login password before they are allowed to connect to specific ports.
By default, incoming Telnet and Rlogin connections are not required to enter the login password. To
configure the Server to require the login password, enter the Set/Define Port Password command.
