For terminals connected to DS300s, you should be able to use TCP/IP (Telnet)
to connect to the HP (if my memory serves me correctly).  I know that the
DS200s don't support TCP/IP (only LAT). I am not sure about the 500s but my
guess is that they are similar to the 300s.

For your LAT only terminal servers, you have a few options:

1. Buy a product such as KiNet (from Ki Research) which implements LAT/CTERM
   on a wide variety of platforms including HP.  This will enable you to
   fully integrate your new HP into the VMS environment (DECnet, etc.)

2. If your VMS systems support TCP/IP, then you can run a LAT/Telnet gateway
   allowing you to connect to the VMS system with LAT, and then passthrough
   to the HP using TCP/IP.  I am not sure if VMS has this capability (I know
   that it exists on ULTRIX)

3. Install a box on your network which will perform protocol conversion
   between LAT and Telnet.  I believe Datability makes such a box.
