IMO a TSR program isn't able to write (or read) above 1 Mb. Is this
a correct view?

No. I always have tested outside Windows using a clean boot without
any memory managers. Now I have started auto232 from the DOS-box
within Win98. I wonder if this is good enough to be safe as I know
HIMEM.SYS behaves different in the DOS-box than if you launch a
program from the desktop.
