7043-150 not displaying on 3151 until OS starts?

Folks,

Have an odd problem with a 43p-150. Have an ibm3151 terminal connected to
serial port S1, and when I boot the system it doesn't show the normal
splashscreen with the "Memory Keyboard SCSI..." text displayed that tells
you when you can hit one of the function keys to boot into service mode or
access SMS. It eventually will come up with some console log messages and
eventually give a login prompt that you can login to and use to access the
box.

When I let the box boot and change the console to the other serial port,
everything works fine. When I change the console back, it stops working
again.

This really sounds odd - I've run diags and they come up clean, has anyone
seen this before or have any idea how to fix it? If it never came up with a
login prompt, I'd assume the port or the cable was bad, but it eventually
comes up with a usable login and the calbe works fine when attached to the
other serial port. So, it's something to do with the port, but I can't
think of what - perhaps something munged in the microcode for this box?

TIA :)
