According to the Causeway DOS extender docs:
"If a Causeway application needs to terminate and stay resident (TSR),
then INT 21 function 31 may be used....No value is required in DX "

I've never tried this, so I can't guarantee anything.
I don't know if this can be done using Euphoria's
dos_interrupt() or not, since dos_interrupt() switches into real mode.
You might have to issue the interrupt by calling a piece of
machine code that you poke in. (i.e. you'll be
executing the INT instruction from protected mode).

If you manage to get something working, please post it
to this list.
