[Coco] Detecting carts

Eprom does no good in OS-9. And Midi carts have no rom anyway. They are just ports. All software, RSDOS & OS-9 for midi is done on Coco side. I know there is a ready state of some sort, and was wondering if that could be checked as midi has an input & output. I was hoping someone from Gleneside would know as it was built by someone in the Gleneside club. I was really just wondering if there was some sort of "cart detect" signal that carts send the coco. Kind of like a carrier detect, but I guess not. The only option that leaves is to default to all drivers off and let the user set the driver and if they get it wrong... thier fault :-) It's not really a major problem, just one I'm trying to avoid.

Well you always have to come back to normal state, if you allow to come out
f the loop the software will hang again, because it did not find the card,
nd you are back to square one. Sins you need the card you would not go on
ith the program anyway..
lso timers in assembler takes a bit of code and maybe you just do not have
he space for it in rom.

and assumes the cart isn't present?
