Since 1989, OmegaBBS had been runing on an Amiga 4000, but a few years ago
(around 2004?) switched to an Amiga One, in which the CPU itself is
emulated at a low level on a RISC chip.  This has the advantage of using
hardware that is about 20 years faster, and vastly more RAM and disk space.

Most of his callers now arrive by Telnet, but I still direct dial in there,
over a serial port modem running on a good old copper POTS line.  With the
death of other BBSes, it's become my primary Internet email connection.

The upgrade to the Amiga One was needed, the Internet email load, and
especially the Spam, was crashing the Amiga 4000.  But the Amiga One, it
turns out, uses the (only) serial port to do diagnostic dumps.  Such a dump
is triggered every time I try to do a file transfer, in either direction. 
This freezes up the port, and locks out that modem so it doesn't answer the
phone until the Sysop reboots.  Telnet file transfers work fine, for those
who have a browser/ISP to telnet in from, as I seldom do.

He installed later betas of the Amiga One firmware, but those locked up
everything all the time, and he had to go back to the earlier beta to get
the CNET BBS software working at all.

Does anyone have a clue on how to get serial modem file transfers working
again?  The diagnostic dumps are useless, how can we (by which I mean he)
turn them off? It's not only files, it's also mail packets, with or without
.QWK formatting, the best way to get lots of them in a hurry so I can work
offline.
 The temporary solution, listing to screen and capturing, has gotten very
old.
