Monitoring of Results:
The transfer process is indicated by dots on the monitor
(of the terminal program).
Note: For the terminal program Telix, the delay
settings between the character and the
lines must be set to “0” for the ASCII pro-
tocol.
9 AT Command Set
All HELMHOLZ communication devices are controlled internally via
AT
commands.
A terminal program is integrated in the HSComm. The
AT
commands can be directly
entered at the menu item “Terminal”.
Alternatively, we recommend the terminal program TeraTerm by T. T. Teranishi. The
free software can be downloaded at
http://www.vector.co.jp/authors/VA002416/teraterm.html.
Each
AT
command starts with the letters
AT
and ends with a “Carriage Return” (CR).
Capital and small letters will both be accepted, but the leading characters must be ei-
ther ‘
AT
’ or ‘
at
’. The command line is evaluated after the modem receives a return
command. In the description, a parameter with the letter “
n
” means that it can have
various values.
For example,
ATL<n>
, where '
n
' can have the value 0 or 3, e.g.
ATL2
(medium vol-
ume). For commands which expect a parameter but don't have a parameter, the mo-
dem will automatically assume the parameter 0. For example, the commands
ATZ
and
ATZ
will have the same effect.
The factory settings are marked “(default)”.
The standard end character is “return” (0Dh) or “
<CR>
“. “Return” may not be
entered after “****” or “+++”.
The commands are acknowledged with “OK” or “ERROR”. A com-
mand that is being edited will be interrupted by any further incom-
ing character. Therefore, the next command must wait for acknowl-
edgement to avoid the deletion of the current command.
