Detach method?

Is there an equivalent detach method that allows you to disable a MODSERIAL interrupt and detach the ISR you attached to it in the first place?

Question relating to:

Did you try attach(NULL); ?

Hello,
If you would like just to detach your ISR then attach a 0 (or NULL), as suggested by Andy. 

modserial.attach(0);


However, this will not disable the interrups (only no user ISR will be called from that moment on). If you'd like to disable interrupts, then I think you should call the disableIrq() member function.

can you give an example on how you would do that?

Of what? Calling .disableIrq()? Which part are you struggling with?

Btw do remember that if you really disable the MOSERIAL irq, you disable the library effectively.
