Communication guide

[quasarix]

Greetings!

My friend has old old machine EMCO CNC-330 lathe/turn that has Siemens or my guess Fanuc system 6 control (with Siemens servos).
Machine works good, but it has no regular display, only red diodes display.
My problem is i cant figure it out how to use communication RS-232 port.
Machine has read/punch/tape modes, but it just wont sent, i got parameters and all is set as it should be, as far as i know, but it doesn't react when pressing read/punch at all (tried in EDIT/MEM)

If anyone has some tips/help, i would love to hear it

I think you have a "3000" control, most Fanuc 6M and 6T have a crt where you can see your programs, parameters a so on.
You may want to take some photos of the control so I may help you further .
