Serial communication in linucnc was created by aleksamc

I have few Input/output boards that use serial communication protocol ANSI 3.28 - 2.5 A4.

I want to use hardware converter RS422 to RS485 to connect to this boards.
Each board has ti's own number adress.

Spindle also has similar serial comunication protocol.

Does it's possible to connect these boards to HAL?

RS422 works, RS485 does work for spindle and plasma control already through USB to RS485 converter, so there is a chance.
Not sure, but most probably the RS485 is not realtime, so if you intend to use them for realtime stuff, i would not bother.

I locked open source for this code. Yes, it's possible to use it to other spindles.

I think it will be useful after some editing of source code.
Thank you.

I think, I will better replace this boards with something up-to-date, for example MESA.

That is the best option, for sure.
