Configure the Serial Port
This section configures the RS-232 serial port so that it is compatible
with the Terminal Emulator in Windows 3.1 or HyperTerminal in
Windows 95.
1. Click the Serial Port button on the main Project dialog.
2. Verify that Terminal is selected in the Protocol list box.
3. In the Maximum Length field, type 1.
With the Maximum Length set to 1, only one character is
downloaded to the reader through the terminal via RS-232 port.
If a message is configured, all bar code strings are read and
uploaded to the terminal via RS-232 port.
If the Maximum Length is set to 2, only two characters are
downloaded to the reader through the terminal via RS-232 port.
However, if a message is configured, only 2 bar code data
characters are uploaded to the terminal. The same is true for a
setting
w3.
