E0278: Host Links merged print session did not work on a TWS session

Product: Host Links Gline
Platform: Any
Status: Closed, fixed in 5.01
Last updated: 1997-07-04 12:06:34

If a DSA session is set up in Two Way Simultaenous (TWS) mode
and the host, for some reason, sends 'turn' on this session
and expects to get the turn back, then this session will 'hang'.

The problem has been observed on a merged print TWS session to TP8.
After the 'xxxx is connected' message, the host side sent an empty
data message which gave the Host Links application the turn. The
(print) application knows that if it ever gets the turn, it needs to
give it back in order to get the printdata.  But the session (line
module) ignored the 'give turn request' from the local application
when applied on a TWS session. This stopped the host side from sending
the print data.
