My Appletalk is currently inactive, and my old Performa doesn't feature an Ethernet port. Only serial printer, serial modem, serial keyboard and SCSI. The Port Peek app did have a force open and force close feature, but that didn't change anything. I'm wondering if you're thinking of the "Reset Serial Channel" application. I did find it, but it's not even opening, I only get an error type -192, which I understand to be a 'resource not found' error.

Egad, thou hast re-stoked my eternal flame of Mac hope, yet I'm still stuck...I shall forge on...<...brave, brave Sir Robin...>

Feel free to pelt me with nuggets of wisdom at your leisure....
