[net.bugs.4bsd] Missing ^Q in 4.1a

keith@edee.UUCP (01/12/84)

We have found a problem in 4.1a when transferring a quantity of data into the
machine over a dh line, using say cu. The 4.1a host issues a ^S to temporarliy
stop the flow, but when the buffers are empty, forgets to ^Q it again.
Has anybody else come across this?

This is a long-standing bug in the tty driver from V7 days.  I have
reported it several times to Berkeley, apparently without getting to
the attention of anyone in a position to do anything about it. I will
mail you the fix (relative to 4.1 sources), or can post if necessary.

Changes affect:

	/sys/dev/tty.c
	/sys/dev/ttynew.c
	/sys/dev/ttyold.c

As I don't have 4.2 sources, the changes may have to be integrated
pretty much by hand, as the kernel source organization changed
considerably.  Total changes affect ~10 lines of original source.
