The Buffer Tab
Selecting the Buffer tab brings up a buffer window, similar to Tera Term or
HyperTerminal, where all data from the serial port are displayed.
From this tab, the user can also send commands through the serial port by typing
on the keyboard. This is only applicable if the device that is connected accepts
serial commands.
This buffer window can also be used for troubleshooting for instances when: the
baud rate, device, or serial port is unknown. For example, if the status bar in the
“Instrument Data Capture area states “Receiving…” and no data appear in the
Data Grid or the Charts, click on the Buffer tab to view the serial data. If the
correct device is not selected, no data will be displayed in the Data Grid or the
Charts, but data will be displayed in the Buffer window.
