Buffers and Data Entry
Keyboard Data Entry
Keyboard characters are displayed at the cursor position only when the DOS computer displays
the compose buffer.

If you type while the contents of the receive buffer are displayed, the DOS computer
automatically toggles to the compose buffer and discards the first character typed.

RS-232 Data Entry
Depending on the DOS computer hardware configuration, I/O through up to two RS-232 ports is
supported. These ports can be configured to supply power to a device (such as a barcode scanner)
through the LDS Plus Configuration Utility Platform parameters, Com1Power and Com2Power.
supported. These ports can be configured to supply power to a device (such as a barcode scanner)
through the LDS Plus Configuration Utility Platform parameters, Com1Power and Com2Power.
By default, Com1 is defined as the barcode port and Com2 as the Aux port, but this can be
changed in the LDS Plus Configuration Utility System menu using the RFFileModeCfg
parameter.

parameter.
Data entry from the RS-232 ports into the compose buffer is strictly controlled by LDS Plus. Data
entry from the ports can be enabled by commands from the host computer, by a form as it is
loaded into the compose buffer or from the keyboard. Input from the Barcode port is enabled by
the [Alt]+[3] key sequence and Aux port input is enabled by the [Alt]+[4] key sequence.

Barcode input capability is also affected by the ReturnToWand parameter (see LDS Plus

Send Data
Use the Auxiliary Out [Alt]+[5] key sequence to send data from the compose buffer to an external
device attached to the Aux port.

Barcode Data Entry
The DOS computers support a barcode reading device for reading preprinted labels. You can
activate the barcode reading device from the host computer, when you enter the Barcode Enable
[Alt] [3] key sequence from the DOS computer, or by a form. Barcode data input is possible only
while the contents of the compose buffer are displayed.

Compose Buffer and Automatic Transmit
DOS computers can be configured to automatically transmit data—without pressing the [Enter]
key. When input from Aux or barcode moves the cursor past a specified point, data is
automatically transmitted.
