lathe tool turret EMCO codes

Hello everyone, I installed linuxcnc on a CNC lathe EMCO 50Turn PC, everything works except the tool changer.

I understand that Ineed to write a "small" piece of code to make it work ... I'm not stuck in this area at all.

For information, on the parallel port of the machine, regarding the tool changer, I have two pins plugged in, one is the tool index No. 1 and the other is the feedback info of change Tools ... there are 6 positions on the tool turret.

Could you guide me in the manipes to perform?

This thread may help if your tool changer is close enough to the pc turn 55 forum.linuxcnc.org/30-cnc-machines/27319...55-upgrade?start=110.
