schematic: mark R22 as dot no place
R22 is use to pull the FLAGB output of the FPF2109 high since this
is an open-drain output.
but we actually don't read FLAGB do get the error conditions, thus
thus pull-up resistor is not required.
this change has been tested with a real simtrace device.
trace and card emulation worked with a Nokia 3310.
