Update of /cvsroot/src/sys/dev/ic
In directory nb00:/tmp/cvs-serv105

Modified Files:
	z8530sc.c 
Log Message:
Make zs_iflush not loop indefinitly. Some Mac PowerBooks lie about having
two SCC channels, and can get stuck in an infinite loop. This change
stops after flushing 4 bytes. Might need upping to 8 bytes if we support
85230 ESCC's.
