The Sente sound communications represent a nasty edge case for ACIA use once I hooked those up. I already needed to hack the driver to keep the sound system from dying near the start on many sets. My guess is that the "master reset" command is causing receiver desynchronization or corrupted transmitter output on one or both of the ACIAs. |

It turned out that the hack was itself the cause of this bug. The ACIA reset issue it was meant to work around was apparently cleared up in some previous round of fixes. |
