That looks quite similar to the problem I'm having.

I haven't really followed screen mapping with 32 bit mapping, so I have
no idea where the screen would be. But as this program must run at
hour-intervals, and shouldn't even interfere with the normal ops, I guess
there is no other way to run it except with DOSemu on stdin/out.

I'm starting to think that it will be easier to capture the entire
serial stream, and reverse engr it, protocol and all. I did some
preliminary captures but it seems quite complicated. 

It's really complicated because the machine is 35 km from here, so I
can't really test easily.
