From: Charles Hedrick <HEDRICK@RUTGERS.ARPA> This should really go to INFO-DECNET, but this seems to be the closest thing... Our DEC network expert says that the LAT boxes support TCP/IP. I think he's spouting hot air. Anybody know whether it is true? (I realize that in principle someone could write TCP/IP software for it. The question is whether it exists or there are any announced plans to do it.) Also, does anyone know what a DSRVA is? This seems to be a LAT server for 8 lines at $2600. This sounds almost too good to be true. -------

To add to the confusion our DEC expert claims that LAT is in the public domain and will not be a proprietary protocal. (I have this in writing but I'm not sure if it is true.)

From: (Stephen Tihor) <TIHOR@NYU-CMCL1.ARPA> I had a discussion with the designer of LAT-11 at the Spring DECUS at which time he said that LAT-11 will remain "technically proprietary" until it is stabilized and that then he hoped but others did not that it would be offered into the public domain and/or standardized. He also explained how easy it should be to reverse engineer LAT-11 with appropriate tools or else to pull the protocol out of the source. \\ Stephen Tihor / CIMS / NYU / 251 Mercer Street / New York, NY 10012 // (( DEC Enet: RHEA::DECWRL::"""TIHOR@NYU-CMCL1.ARPA""" NYUnet: TIHOR.CMCL1 )) // ARPAnet: Tihor@NYU-CMCL1 UUCPnet address: ...!ihnp4!cmcl2!cmcl1!tihor \\ -------

Our DEC network expert says that the LAT boxes support TCP/IP. I think
he's spouting hot air. Anybody know whether it is true? (I realize
that in principle someone could write TCP/IP software for it. The
question is whether it exists or there are any announced plans to
do it.)
It's not at all clear what it would mean for a LAT box to "support" TCP/IP;
that's just about equivalent to asking whether a DZ-11 supports TCP/IP. One
sense your expert MIGHT have in mind is that LAT can be run on the same
Ethernet as TCP/IP; the two protocols will ignore each other.
Just what is it you are trying to accomplish through this "compatibility"?
If I gave you a LAT box, what would you do to determine if it was "TCP/IP
compatible"?
Also, does anyone know what a DSRVA is? This seems to be a LAT
server for 8 lines at $2600. This sounds almost too good to be true.
Yup, that's about it. A small, cheap box for connecting 8 terminals to an
Ethernet. I heard it described as $325 per port, which matches your number
exactly.

From: dual!mordor!seismo!harvard!bu-cs!root@BERKELEY (BostonU SysMgr) What would it mean for LATs to support TCP/IP? It would most likely mean they would support the TELNET remote login protocol. Bridge makes a box exactly like this. I doubt *very* much LATs support this although in theory they could (all you need is a CPU and an appropiate communications [ethernet is good] device and the software which is non-trivial but mostly exists already). $325/port? That's hard to believe... No its not, that's currently competitive, perhaps a little on the low side. Within the next 12 months we expect to be spending about $200/port based on vendor's projections and currently spend almost exactly that (between $300-$400.) -Barry Shein, Boston University
