To update the BHT system by using an application program, download an update file to the
BHT and then execute an
OUT statement. Updating the system will take approx. 30 sec-
onds. During updating, the BHT power should be kept on. If an execution program has
been set, execution of
OUT &H60D0, 1 may cold-start the application.
*19
You may specify the size of the empty user area to be defragmented in units of 4 kilobytes.
The size is expressed by two bytes: lower byte on port 60E0h and upper byte on port
60E1h. The setting range is from 1 to FFFFh. (The actually allowable maximum value is
the size of the empty user area. If you specify a value exceeding the size, the whole empty
area will be defragmented.)
To defragment 2048 kilobytes of area, write as follows:
2048 kilobytes/4 kilobytes = 512 (200h), so
OUT &h60E0,0 ’Sets 00h to the lower byte
OUT &h60E1,2 ’Sets 02h to the upper byte
If "0" is set, the whole empty user area will be defragmented.
*20
To defragment the drive, set "0," "1," or "2." Setting "1" or "2" will display an absolute bar
graph or relative bar graph indicating the defragmentation progress during drive defrag-
mentation, respectively. The bar graph will disappear after completion of defragmentation
and the previous screen will come back.
To defragment the drive while showing a relative bar graph, write as follows:
OUT &h60E2,1 ’Defragment the drive showing relative bar
graph
*21
To activate the remote wakeup, set "1"; to deactivate, set "0."
*22
Set the transmission speed to be applied for remote wakeup.
*23
You may set the timeout length during which the BHT will wait for proper data (specified
remote wakeup character string) after receiving any data via the CU from the host.
