Revision 1.0

The commands you type will not appear in the HyperTerminal window unless you set up HyperTerminal to
do so. Only the response from the HP-BLU will be displayed. If you prefer to see the commands you are
typing on the HyperTerminal window click the
File
menu and execute the following sequence:
File
→
Properties
→
Settings
→
ASCII setup
→
“
Echo typed characters locally
”
→
OK
In the HyperTerminal window, type
*VER.
If the response is the version of your HP-BLU, you are
successfully connected and ready for serial command action.
In some cases, the HP-BLU has connection problems that can be solved by adding a character delay. To
adjust this delay, click the File menu and execute the following sequence:
File
→
Properties
→
Settings
→
ASCII setup
→
“
Character delay
”: add a few milliseconds of
delay
→
OK
When you end the session, HyperTerminal asks if you want to save your settings. To avoid inputting the
communication parameters again in the future, save by clicking Yes. Clicking on the session name will open
the connection using the saved settings. To avoid re-entering the string of commands, put a shortcut to this
file on your desktop: search for the file name, select the file. Right click and select Shortcut in the drop-
down menu.
4.3. SERIAL COMMAND FORMAT
Commands are sent as text strings. The response will either be data or an empty string.
All text commands must begin with a trigger character (*). Without the (*) character, nothing will happen.
You do not need to end with a line-feed and/or a carriage-return. Parameters must NOT be separated by
spaces. Characters must be capitalised.
In case of an error, the reply string is one of the following:
“Invalid Command”
