[net.notes] miscio.c & ttyerase/ttykill

mclure@sri-unix (07/29/82)

There are some problems with the miscio.c recently distributed.

	1) it does not import the ttyerase/ttykill hacking to 
	   reading numbers. Instead, it hardwires backspace
	   and @.

	2) the code that handles ttyerase/ttykill assumes that
	   the erase and kill characters are single characters
	   (e.g. "/10 /10") which is not necessarily true. 
	   On 2.8/4.1 using the new terminal driver, many users
	   have set their erase/kill to things like ^? (delete)
	   and ^U (control-U for TOPS-20 fans) and ^X (control-X
	   for TENEX fans)
