These two CCL scripts are used with AppleTalk Remote Access and the Global Village Teleport Gold and PowerPort Gold and Silver modems respectively. They allow the user to choose the maximum speed that they wish to communication at. I wrote this because some of the phone lines I dial in from a pretty bad and although the modems may eventually connect at 14.4 they soon lose they carrier etc. and crash. It is much easier in this situation to simply try and connect at a lower speed. Previously, I had hacked some CCL's and each one would connect at a certain speed. However, this is tedious as it the appropriate script has to be selected each time from the Remote Access Setup Control Panel. Using this CCL I just choose the speed I want and that's it.
Note: The PowerPort and Teleport modems have a very different command set and functions. When using either 12000 baud or 7200 baud with the Teleport that is the only speed at which you can communicate. ie If you try to connect to a modem that does not support these rates then the connection will fail. However, with the PowerPort series communication can take place at a lower rate if 12000 or 7200 is not supported.
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 with 300,1200,.... to select the appropriate speed via either modem 'AT' or ARA 'serrest' commands.
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.
