Section 3. Commands; Data Format; Responses - Elo TouchSystems Entuitive ET1725L Series User Manual

This section describes all of the commands that can be used with the MagTek Windows Device
Drivers. Some commands require parameters to indicate to the driver exactly what function is to
be performed. While there are a few device-specific commands, most commands can be used
with any device.

DATA FORMAT

All commands sent to the driver and all responses received are strings of printable ASCII
characters delimited by
and response strings begin with the character
separated with one or more white spaces. The driver accepts space
space characters.
A command delimiter sent immediately after the previous
command delimiter is interpreted as an empty command and is
ignored by the driver.

RESPONSES

All responses to the transaction commands are formatted with fixed fields, to allow them to be
parsed either by scanning for white spaces or by using constant offsets into the response string.
In the descriptions of the commands found later in this section, the arguments sent with the
responses are shown in their respective locations but may not indicate the exact number of
spaces. The actual responses are sent in a fixed-field format, as shown in the following table:

the field and begins in location 12. Status
information is right justified in the field (with a
trailing space) so the SS value will always be located
at positions 21 and 22.
