PORTB / ICSP comm?

Is this the culprit?

: init-out
    TRISB 2 low
    TRISB 3 low ;

Nope.  ICSP pins are RB7-RB5

It seems to really be the interrupts.  Whenever I switch on one of the
timer interrupts the comm gets messed up.  It probably misses pulses.

I seem to recall that the ICSP hardware's pulse size can't be changed,
but I beleive it does keep the data stable after the pulse.  Is there
a way to let the hardware detect the pulse?

PORTB 6

There is the interrupt on change mechanism.

The question is whether it is worth to spend time to do this.  Let's
just briefly look at the IOC mechanism.
