OK I found some sample script in CW 3.5.3 and it also has the schematics for the multitarget board.
Though does anyone have a sample script for 4.x?
Still struggling with settings, like what should be the clock for smartcards? Docs say somewhere between 1 MHz and 5 MHz, which is not helpful. Also not sure if it can change.
Do I use the connect_cwlite_simpleserial.py for connection or do I have to specify different target. There seems to be a separate GUI component in the sources, a descendant of TargetTemplate, but not sure how to use it.
EDIT: so after connecting to oscilloscope it seems the card reader tries 4.7 V and 3.75 MHz. Not sure though if a modern smartcard would work with 3.3V.
EDIT2: after mucking a lot with CW 3.5.3 and 4.0.4 I finally found where the option for smartcard target and settings are. But the target won’t connect:

Tried setting the clock to 3.75 MHz, but I don’t understand why can’t I set it before connecting. But any attempt to get ATR or send APDU fails with the above message.
