[Coco] Interbank Incident for Drivewire ?

[Juan Castro]

Is there a neat POKE I could use to change the speed to a lower value
when loading CoCo 1 DW from the Cloud9 site WAV? I'm having difficulty
making it work. Whereas the CoCo 3 version works like a breeze. And
yes, I tried changing the server speed to 38400.
