M42 in old Marlin 1.1.x

Hi,

I'm working with a fairly old Marlin setup and want to use M42 to switch some pins.

In the Code documentation there is a line saying "Set the pin mode. Prior to Marlin 2.0.9.4 this is set with the M parameter." I've been trying to find some documentation on this, but unfortunately can't.

Does anyone know the correct usage of M42 and M-value in Marlin 1.1.x.

Many thanks,

Ingo

Marlin 2.0.5.2 - 2.0.9.3 uses the M parameter to set the pin mode: 0=INPUT, 1=OUTPUT, 2=INPUT_PULLUP, 3=INPUT_PULLDOWN. In Marlin 2.0.9.4 and up the T parameter is used instead.

... I'm remembering something like "M42 P2 S255" for activating a Pin D2 (and accordingly "... S0" to deactivate)
