Doug McDonald writes about a bug in HIMEM.SYS which many seem to think is
not. However, I think I have uncovered yet another annoying feature of
HIMEM.SYS. I have HIMEM.SYS installed, DOS 4.01 (same with DOS 3.3), and 
Carbon Copy 5.0. I also have a modem installed on COM 4 (though it 
doesn't seem to matter what COM port I use). When I start up CCPlus, it
complains that com port did not respond to IRQ test and drops back to
the C prompt. If I deinstall HIMEM.SYS, everything works like a charm. I
don't believe that CCPLUS uses extended memory at all, so this 
interaction definitely *seems* like a bug. Anyone know what could be
happening?
