Escape Timeout
The Escape Timeout is the length of time (in ticks , or 60ths of a second) that the 9160 G2
will hold an “ESC” received from the host, and consider the next received byte to be part of
an escape sequence. The range is
0 to 255 , with a default value of 12 .
When this timeout has elapsed, the host will have to send another “ESC” character to start
an escape sequence.
Note: This is especially important when an ESC is at the end of a data packet.
Threshold
The Threshold is the minimum number of bytes of update data for the mobile computer
screen which must be received from the host before the 9160 G2 will store the screen as a
new “saved page”. The range is
0 to 999 , with a default value of 200 .
Important: The Page Saving parameter (page 291) must be enabled in order to change
the value in the Threshold parameter.
Echo
If this parameter is enabled , the 9160 G2 uses “Smart” Echo . This mode reduces the
amount of data sent to the mobile computer by decreasing the number of radio
transmissions.
Ordinarily, when a character mode application is being used, each keystroke is sent to the
host in one transmission, and the character is echoed by the host in another transmission.
When
“Smart” Echo is enabled , the 9160 G2 will not send the host echo to the mobile com-
puters if it matches the data sent from the mobile computer. Thus, the number of radio
transmissions is reduced.
This mode also reduces or eliminates the delay between typing a character on the keyboard
and displaying the character echoed by the host. The maximum number of characters
waiting for echo is
25 . Any additional characters will be sent to the host but not displayed.
Notes:
1. This parameter also determines whether an ANSI parameter query is sent to
the mobile computer.
2. “Smart” Echo also needs to be enabled at the mobile computer (refer to the
User Manual of the relevant mobile computer).
