These scripts are modified versions of the standard Apple CCL scripts (v1.2, 30 Oct 98) for the G3 Series internal modem. Put them in System Folder:Extensions:Modem Scripts, select one in the Modem control panel, and try dialling your ISP using OT/PPP or ARA 3.x. I have also provided the text versions of each script (the files with a .txt suffix) for anyone who wants to see what's inside.
The '56K' and 'V.34 Only' scripts have been modified to avoid malicious forced disconnects, which can be caused by 'pinging' your machine with a disconnect string. No other changes have been made, so the scripts will perform just like the standard ones in all other respects.
The '56K RB' version is additionally modified to reduce the modem's sensitivity to short loss of carrier from the ISP, and to change the way the modem carries out some high-frequency tests that are part of the V.90 synchronisation process. Without the latter, the internal modem may not connect at V.90 speeds with an ISP that uses 3Com (was US Robotics) TOTAL Control equipment.
The '42.6K' to '50K' versions additionally restrict the modem to those speeds, which tends to result in more stable connections as they don't push the modem and the line to their limits. A number of people who have tried these scripts have found they get connections more often, and those connections last longer without disconnects. You should not need to go much slower to gain stability, so the performance penalty is a reasonable price to pay for more stable connections.
If you get unstable connections with the '56K RB' script, try the script which has a speed limit just below your normal connect speed - i.e. if you normally connect at 48000 but get frequent disconnects, try the '46.7K' script. If you still get disconnects, try the next-slowest script and so on down until you get stability.
Of course, these scripts won't improve modem performance for everyone, but they're worth trying. Please let me know if you experience any difficulties with them.
