Subject: Global Village Variable CCls
This CCL scripts is used with AppleTalk Remote Access version 2.0.x and the
Global Village Mercury, Gold and Silver modems, both PowerPort and
Teleport. They allow the user to choose the speed that they wish to
communication at. It is based on the Global Village Merc/Gold/Silver script
and my original hack for the Teleport and PowerPort modems
In this version I have limited the connection speeds to only the one
specifed using the AT command S37=??. I've check it out with a GV Teleport
Gold and Powerport Mercury, but only at speeds upto 14.4kbs (I've only got
one Mercury).
How It Works:
The ARA CCL language supports a command 'ASK'. This allows the user to type
in a text string. This string can then be printed, either to the screen or
to the modem. (As far as I know I can't do any string comparisons with it,
or access it in any other way!! If any one knows any different please let
me know.) This string is then sent out to the modem which has had 'echo'
enabled. The string is then read back in from the modem and is then
compared with1200,.... to select the appropriate speed via modem
'ATS37=...' .
Please note that these scripts have no yet been approved by Global Village
and are supplied as is with no warrenty etc. However, they work for me and
that's all I was ever bothered about anyway.
Have fun , and let me know if there are problems,

ps I'll get round to writing the CCL for the Platinum when I get access to
the AT command set and the report codes from the modem. (Of course the
easiest way is for Global Village to send me a modem...)
