CONVERT FROM CHAR A PROPERTY
Property ID: 26 (0x1A)
Property Type: Byte
Length: 1 byte
Get Property: Yes
Set Property: Yes
Default Value: 255 (0xFF) (None)
Description: The value is a byte that represents the ASCII value of a character transmitted
by the device as keystroke data that is to be changed into a string of ASCII
values prior to being transmitted by the device as keystroke data. The string
of ASCII values that this value will be changed into is contained in the
Convert To String A property. If the value of this property is set to 0xFF, no
characters will be changed into the string. For example, if you would like a
carriage return to be sent as an end of text character you could set the
Convert
From Char A property to 0x0D (carriage return) and set the Convert To
String A property to 0x03 (end of text). If you would like a carriage return to
be sent as two carriage returns you could set the Convert From Char A
property to 0x0D (carriage return) and set the Convert To String A property
to 0x0D 0x0D (carriage return, carriage return). If you would like a carriage
return not to be sent you could set the
Convert From Char A property to
0x0D (carriage return) and set the Convert To String A property to no string.
This property is stored in non-volatile memory, so it will persist when the unit
is power cycled. When this property is changed, the unit must be reset (see
Command Number 2) or power cycled for these changes to take effect.
