If the screen is blank, or becomes unreadable or garbled, right click in the Xpert display area.
This sends a command to the Xpert retrieve again the contents of the display. To do this on the
PocketPC, tap and hold the stylus on the screen to access the main menu, and then select
“Update Now”.
Note that while you operate Xpert from XTerm, the Xpert’s physical display (if it has one) will
also be changing. If someone is looking at the screen while you are operating the Xpert, they will
see all that you are doing. Both the touch screen and PC are active at the same time with the
same priority so don’t try to work on the Xpert at the same time.
XTerm is very smart when it comes to knowing when and how to update its display. However,
the nature of serial communications sometimes causes screen updates to lag slightly, or become
garbled. As an example, log-in to the Xpert and select the different tabs of the Xpert display.
Notice that it takes time for the Xpert to switch from on tab to another. If you are connected at a
baud rate slower than 115,200, the wait for the display to update can be long. If you select a
control and don’t see an immediate response, wait a bit and try again. Do not click controls
rapidly as this will very likely translate into undesired behavior.
When using the desktop version of XTerm, you can use the desktop’s keyboard as if it were
connected to the Xpert. For example, instead of using the Xpert’s virtual keypad (shown below),
use your keyboard. The characters typed are sent to the Xpert’s keyboard buffer.
When exporting logs from Xpert using XTerm, XTerm assumes you want to save the exported
log on your local PC and so offers a Save-As dialog on the local PC (see below: desktop PC
