I guess it interfaces to a bisync line?
Out of the box, the RSCS that comes with VM/370 has a driver called DMTNPT.
The comments at the top of it say:
* MODULE NAME -
*
*
* DMTNPT
*
* FUNCTION -
*
* THIS RSCS LINE DRIVER PROVIDES SUPPORT FOR THE 2770,
* 2780, 3770, AND 3780 TYPE NON-PROGRAMMABLE TERMINALS.
*
Perhaps this covers the 3774? If not, I don't see any problem coming up with
a derivative driver that would work.
I expect MVS 3.8j has similar capabilities but I don't know MVS well.
The real challenge is either to interface Hercules to a real bisync line or
to interface the 3774 to an emulated bisync line.
