Kbd Modes
Echo Mode
This parameter selects echo mode for the 8525/8530. The available modes are
“Local”, “Host”, and “Smart”.
Local: In this mode, any character entered using the keyboard is displayed
before being sent to the host. Certain keys cause additional action
at the 8525/8530, as shown in Table on page 213.
Host: In this mode, the vehicle-mount computer sends all keyboard
entries to the host and displays only data received from the host.
Smart: This mode reduces or eliminates the delay between typing a
character on the keyboard and displaying the character echoed by
the host computer. The 8525/8530 displays all printable characters
on the screen before sending them to the host. The vehicle-mount
compares the characters echoed by the host to the characters placed
on the page and fixes the display if the host echoes are different.
The maximum number of characters waiting for echo is 25.
Any additional characters are sent to the host but not displayed.
When the 8525/8530 is in insert mode, smart echo is disabled.
