Thanks for the response, Nick, I'm almost there and just one further query:

Been there, seen that, kicked self in butt once I realized the port I
was trying to use as a serial terminal was also configured as a serial
console for the terminal machine (D'oh!). Basically, the two machines
start bouncing back and forth off each other, and nothing works as
desired.
Yup, makes perfect sense now.

And that tells us more.
Note that it's pccom1 and pccom2, but no pccom0... pccom devices are
ISA devices, so they can't share IRQs with PCI devices (though, of
course, PCI devices can share IRQs with each other). So that's why
com0 didn't work, and the IRQ conflict won't make com1 and com2 work
very well...
Take a close look at your machine config (most likely, the BIOS setup
program), you will probably find non-standard configs for the two
serial ports. You might need to "tag" IRQ 3 as "Reserved for ISA" or
similar.
The Aptiva has an anaemic BIOS program, but by disabling one of the
two serial interfaces I now appear to have eliminated IRQ conflicts
and acquired a working serial console - BUT I lose nearly all of the
dmesg(8) and init(8) output at boot, with it being directed to the
screen instead. I also note that boot(8) tells me I have com0 and no
com1 (which is expected since I disabled it in the BIOS) whereas
dmesg(8) tells me I have pccom1 but no pccom0 and this seems a little
strange to me.
To clarify, boot(8) tells me I have com0 available at boot. So in
/etc/boot.conf I tell it:
set tty com0
and it switches to the console but all that is output to the console is:
OpenBSD/i386 BOOT 2.10
boot>
booting hd0a:/bsd: 4966344+867848 [52+255872+237161]=0x608d64
entry point at 0x100120
That's it for the output seen on the terminal, at this point the
dmesg(8) and init(8) output is directed to the screen. Then when
getty(8) is executed interactivity for _both_ the keyboard and the
serial console are restored.
Any further thoughts will be appreciated; dmesg(8) and ttys(5) are
included below:
