    Well, we're a year down the road and now running VMS V6.2-1h3
    on all the Alpha 200 4/100's on the production floor ('bout 120+).
    We are still having the same "periodic" hang of the TTA0 and OPA1
    serial ports.  The customer is sending Regis graphics code from
    a PDP to a DECterm on the Alpha's running a SET HOST/DTE session.
    I've applied the following patches:
    	ALPSYS06_070
    	ALPOPDR02_062
    	ALPTTDR02_070
    with no apparent success.  By "peridoic" hang I mean that on occasion
    the port will stop receiving data, but if you wait long enough (a
    minute or so) it will continue processing data w/o and data loss.
    
    Another situation has come to light during analysis of this problem.
    Connecting a Hayes 144 Optima modem to either of these port using the
    same SET HOST/DTE setup causes basically the same problem.  The
    connection is made thru to logging in to the server then onto a
    node successfully.  Then after a couple minutes of processing time
    the DECterm session will hang.  Also if you wait long enough the
    data will eventually be transmitted a character or two at a time.
    
    Any ideas,
    Ed Gallagher
