Mode Commands
Line Mode and Immediate Modes
Data can be sent and interpreted one line at a time,
or be processed immediately. The default setting is
for “Line Mode” (~L). This is the recommended
method of use. Line Mode is better for automated
control and provides more reliable interaction.
“Immediate Mode” (~I) can better simulate
keyboard operation in some cases. Warning:
Immediate mode provides no throttling of input, thus
data sent to the KeyAT can be lost if it exceeds the
keyboard input rate of the computer.
~L
Line Mode - Set to a line oriented basis,
each line must end with an <ENTER> or
<CR>, hex OD.
~I
Immediate Mode - Data is interpreted 'on-
the-fly'. Note that in this mode <ENTER> or
<CR> (Hex 0D) is passed on to the
computer. Caution should exercised in
Immediate Mode, as it is easy to overrun the
PC’s keyboard receive buffer.
