Below is the "loadable driver" I mentioned, but I think I should apologize for any ambiguity in my statement above: I do NOT have the source code to an actual ph driver, only to this simple "driver" that essentially makes an in-memory patch to the normal driver. Remember that this will completely prevent any kind of "VOICE" mode access to either phone line. The phone manager will no longer work. I threw in an "Install" script which has not been tested, but should work, or at least give you the right idea. A lot of people asked for this, and I think I lost a few of their names, so I decided to just post it. -=] Ford [=- "The number of Unix installations (In Real Life: Mike Ditto) has grown to 10, with more expected." ford@kenobi.cts.com - The Unix Programmer's Manual, ...!sdcsvax!crash!elgar!ford 2nd Edition, June, 1972. ditto@cbmvax.commodore.com #! /bin/sh # This is a shell archive, meaning: # 1.
