[plug] Any kernel hackers out there...?

[Kim Covil]

Great... :)

I'll spend some time trying to get this working tonight and tomorrow
hopefully... If I can get it basically working I have some help from
someone in the empeg community who says he can tidy it up at the end.
But as he is busy working on other stuff, and my problem is pretty
specific to my empeg I will get a full solution quicker if I can get the
basics running myself.

Cheers

Kim

PS I use the empeg for music while sitting at my desk at CSIRO so does
that count...? :)

A simple idea might be to disable the interrupt and pinch the bit of code from the ISR that polls for received chars and then the bit that fetches the chars from the serial hardware. Stick that in a loop with a timer test to spin for (say) 10 milliseconds after transmit (the tuner might take longer than that to respond .. experiment). The driver source will tell you what to do. The timer code may not be as evident. This solution is untidy but not much different to sensing if hardware is present on the end of a driver I spose.
