5.1.2.3 Parity, Character Size, and Stop Bits
The default character size of 8 data bits can be changed to 7 data bits. Similarly, the default stop bit count
of 1 bit can be changed to 2 bits. Parity is normally None, but can also be Even, Mark, Odd, or Space.

5.1.3 Virtual Ports
Incoming Telnet and Rlogin connections are not associated with a physical port. Instead, they are associated
with a virtual port, port 0, which serves for the duration of the connection.
Each virtual port is created with a default set of characteristics. The Set/Define Port commands (starting
with Define Port Access on page 12-15) can be used to customize a virtual port during the Telnet/Rlogin
session; however, these customizations cannot be saved. The port reverts to the default set of characteristics
once the session is closed.
To make configurations that apply to all virtual ports (all future Telnet/Rlogin connections), use Define Port
commands and specify zero as the port number. All port settings can be configured for virtual ports except
those that don’t make sense for virtual ports, (i.e., DSRLogout, DTRWait).
For example, the command in Figure 5-9 makes all ports process the Break key locally rather than passing
it on to the remote service.

Note:
Virtual ports cannot be configured with Set commands, they can only be
configured with Define commands.
Note:
Use the List Port command to view virtual port characteristics.
