Yes, I know the problem well.  We here at Baltimore County Gov't have an
 
HP3000 series 948 supporting over a hundred terminals.  It is a mix of
 
2392A's, 700/92's and PC's using Advancelink.  The HP2392A terminals
 
were originally designed to use Enq/Acq protocol (on the Classic
 
architecture).  When HP introduced the RISC architecture, they
 
eliminated Enq/Acq as the terminal protocol and replaced it with
 
XON/XOFF.  The default for the HP2392A's is RecvPace: None and
 
XmitPaced: None.  Here is what you do to make them work:
1.  Press the User-System key to get the configuration softkeys
 
displayed on your screen.
2.  Press the F8 key (config keys).
3.  Press the F3 key (datacomm config).
4.  Tab the cursor down to the RecvPace box and press next choice until
 
Xon/Xoff is displayed.
5.  Tab over to the XmitPace box and change it as above to Xon/Xoff.
6.  Press Save Config.
 
It doesn't seem to matter what setting you have for Enq/Ack, the
 
terminal can now handle block mode with buffer overruns.  Also make sure
 
that your batteries in the terminal (two size "N") are replaced when
 
they lose configuration settings.
