I am replying to my own post to make some corrections on my original description and diagnosis of a problem that occurred on our new Performa 6300. I orginally observed that when Appletalk was turned on, Zterm 1.01 would lock up when the program was started. This in turn caused a serial port lockup that would not go away after restart. The serial port lockup was accompanied by an inability to restart or shutdown the computer from the Special pulldown menu and Teleport control panel could not tell what kind of modem was connected. I have since observed that this apparent incompatability between Appletalk and Zterm happens only when Apple Remote Access is set to receive a call. Furthermore, this only occurs when Serial DMA is installed on the system. Ultimately, the cure has been to remove the Serial DMA extension and use the Serial Port Arbitrator that comes with ARA instead -- a simple and obvious solution with the benefit of hindsight. It was unclear at the time that I installed Serial DMA whether or not it was compatible with (or even intended for use in) the Performa 6300. It is clear now that at least for this purpose it is not.

The 5200/6200/6300 families do not have geoports nor any type of
serial dma and thus the extension does nothing for us... we'll be
waiting for Copland for speed increases once the various mode
managers and device drivers are all native.
