unknown SYSV5R2 ioctl() commands...

[Michael E. Burg]

Hello!! I was looking through /usr/include/sys/{termio.h,ioctl.h} on
our 3b2/300 and found a couple of ioctl() commands that I couldn't find
any docs (or comments) for. They are:

	termio.h:
		LDOPEN, LDCLOSE, LDCHG, LDGETT, LDSETT

	ioctl.h:
		DIOCGETC, DIOCGETB, DIOCSETE

	Anyboby out there in net-land have any idea what these commands
are and do??

		Thanks,
