So the reason the REX is not working might simply be the fact that the System ROM calls in REXMGR are all wrong and not so much a hardware issue. Aren't the European models lacking a modem? This would mean the system ROM is different than the "standard" M100 ROM.
Oh, and the way I tested the REX was basically the same as what you had described … put it in an CALL 63013.
