Subject: Tip to a hayes modem doesn't allow a pause character +Fix
Index:	usr.bin/tip/aculib/hayes.c 4.3BSD +Fix

Description:
	The code in tip (acu.c) stops a phone number on a ',' character
	as documented in phone(5), thus not allowing the ``normal''
	Hayes pause character in a number.  Neither of the documented
	characters, '=' and '*', affect a pause.  '=' works correctly
	for a USR (courier) modem.
Repeat-By:
	Try to have tip dial a hayes modem type with a ',', '=', or '*'
	indicating a pause.  None will work.
Fix:
	Choose '=' as the pause character for hayes modem type.
	The attached code solves this problem at Elxsi.
