Slave devices
Slave devices do not support the display of ASCII Entry variables in
messages. ASCII Entry variables are removed from a message by the
master MessageView terminal before the message is slaved.
Although slave devices do not display ASCII Entry variables in a
message, the master terminal does display them whenever it displays
the message.
ASCII Triggering devices
Tag Node Name and Address attributes are ignored by an ASCII
Triggering device. They may be omitted when creating applications
for use with such a device.
