Huh? Something on the serial interface was interfering with Firebird???
The serial interface programs runs continuous as a system tray app.
An NT service hooks data out of it via a shared memory interface and
writes it to Firebird. The programs always run together.

The serial port program is 3rd party so a little tricky though I believe it is
written in C++ Builder from a discussion I had with their developer while
getting the shared memory link to work. I would be very interested to what on
earth could cause interference to Firebird.
