Sending Data To The Host
6.8.2 Sending Data To The Host
8525/8530 vehicle-mounts running ANSI sessions transmit characters to the host as
soon as they are typed. The 8525/8530 provides parameters that determine when the
computer transmits characters to the host.
The 8525/8530 can be configured to transmit after a number of characters are typed
in (the “Xmit Count” parameter) or after some time has elapsed (the “Xmit Wait”
parameter), or both. This reduces overhead on the radio link and improves response
time. See page 209 for more information about these parameters.
You can also determine whether the 8525/8530 transmits immediately after the
[ENTER] key, an arrow key, or a function key is pressed.
The 8525/8530 computer also responds immediately to the device attribute requests
“CSIc”, “CSI0c” and “ESCZ”.
Note: For a more detailed description of the parameter settings for ANSI,
refer to “ANSI Settings” on page 201.
