[BRLTTY] Papenmeier EL40C apparently detected as EL40S

[Jeanette C.]

Hello Dave,
attached is the log now with the inpkts log option. And you are right, 
RoutingKey1 is the row diirectly behind the braille cells. I don't know why I 
mixed them up. So, I pressed: 
RoutingKey2 1, RoutingKey2 2, RoutingKey1 1, RoutiingKey1 2 and easy access 
bar down + RoutingKey1 1
The device does not have an internal menu, not that I can reach. But when 
power is connected it briefly identifies itself as an el40s. It still has the 
easy access bar that only moves one step in each direction. -- It is a strange 
situation.

Best wishes,

Jeanette

> So brltty is thinking that what you have is an EL40S. That model identifier - 85 - is being sent by the device itself so, for whatever reason, it's advertising itself as an EL40S. Does it maybe have some kind of internal menu where you can set this kind of thing?

> you mentioned looking for an EL40C-specific driver. Brltty doesn't have that. Its Papenmeier driver looks at the device's model identifier value to decide which actual model you have. And, yes, 85 is indeed the model identifier for an EL40S. The EL40C has the model identifier 95.
