When sending data, all 8 bits must be provided. The MICR Plus will execute the command but
it will not reply. The new settings become effective immediately. To make this command
permanent, use the SA command described below.
If no data is sent, the MICR Plus responds with the current settings for HW.

HW PARAMETERS
Disable/Enable Y Option
Enable this option when using a Y-cable to connect an additional device on the RS-232 Host
Port. This option allows the MICR Plus and the additional device to receive/transmit data from
the Host.
One important consideration is to determine how the MICR Plus should respond to all data
received from the Host. This response is controlled by the Invalid Command Response. (See
SWC Command, above.)
Disable/Enable Tracks
Each Track can be enabled or disabled individually. The tracks are always transmitted in
ascending order: TK1, TK2, TK3. For example, if TK1 and TK3 are enabled and TK2 is
disabled, the reader will transmit TK1, TK3.
