Well, I've made a bit more headway in troubleshooting the thing.
It looks like Concurrent is crashing before it sets up the serial ports.
I turned on all serial port debugging, and the only serial port activity
is dosemu's initialization and shutdown when I kill the process. No
further serial port activity is being logged.
Here's the tail end of the log:
DISK: /var/lib/dosemu/cdos-only.img: Trying to read 9 sectors at T/S/H

DISK read @1/15/0 (9) -> 0x98e00 OK.

RTC: alarm check e=0x2
...more SIGNAL messages...
RTC: cmos update 16:39:30
RTC: alarm check e=0x2
...still more SIGNAL messages...
and so forth.
I'm afraid I don't understand dosemu's architecture quite enough to know
what these incessant signals mean. How would I troubleshoot this?
