One of the files included with Sunlink-X.25 is:
	/usr/sunlink/x25/sys/sun3/OBJ/zs_sdlc.o

When it is linked into the kernel, device "zss0" is ttya in sync mode and
"zss1" is ttyb in sync mode.  I am running X.25 over my 3/50's ttyb port
now.  I don't think Sun provides that module except as part of a purchased
product.
