TELNET Symbiont Changed Between VMS Versions?

[Robert Atkinson]

We're running a production system on VMS 7.2-2 and testing our upgrade to VMS 7.3-2.

One thing we've found is that we are getting blank pages at the start of some printouts, when we send setup modules. In this case, an escape sequence to put the printer into landscape.

This seems to be caused by the TELNET symbiont on 7.3-2 sending CRLF, whereas VMS 7.2-2 only sends CR.

I've attached the trace dumps for both.

Has anyone else seen this problem.

Robert.

And the other trace file....

Robert,

Telnet isn't from VMS but TCPIP. Which version of TCPIP youre using ?

Do you have also set up the needed TCPIP$TELNETSYM_ logicals ?
These logicals must be active before starting the queue. So if logicals are changed, the queue need to be stopped and started. These logicals are only used when the queue is started. So sort of dynamic for new queues.

I think the following logicals wil help you:
TCPIP$TELNETSYM_RAW_TCP = "TRUE"
TCPIP$TELNETSYM_SUPPRESS_FORMFEEDS = "35"

Minimize and structure youre messages and environment:
TCPIP$TELNETSYM_LOG_KEEP = "3"
TCPIP$TELNETSYM_NO_OPCOM = "TRUE"
TCPIP$TELNETSYM_SCRATCH = ":[TELNETSYM]

You may have lost a logical (2nd bullet).

If not what are/were your tcp versions ?

The producation system is running 5.1 Eco3 and the upgrade node is running 5.4, so definitely a change there.

I've checked the logicals, and everything seems to be the same.

Any other ideas?

Robert,

Having compared the dumpfiles, I don't see the difference in CR/LF and CR. In boths dumps, records seem bo be ending with the combination (hex) 0D0A.

Assuming that the dump are from the same (or a very similar) file - the second has one 80-character line moreat the end - most significant is a difference in initialisation. I don't know whether this is a symbiont thing, but I hardly think that would make a real difference.

I would take a good look at the form definitions.

Willem,
if you look at the 'initialisation' (where the setup module is sent) for the text "&l2E", this is where the LF is sent as an extra piece of data.

I believe this is causing the blank page, but why are 5.1 and 5.4 doing different things?

Robert,

http://h71000.www7.hp.com/doc/73final/6526/6526pro_042.html#telnetsym_formfeed_suppression

Your logicals holds a different value or the behaviour changed. As I understand it, it should contain 35 or you will get the formfeeds.

[Robert Atkinson]

Willem, both systems are set the same :-

Beta:
(LNM$SYSTEM_TABLE)

"TCPIP$TELNETSYM_IDLE_TIMEOUT" = "0 00:00:10.00"
"TCPIP$TELNETSYM_RETRY_INTERVAL" = "0 00:00:30.00"
"TCPIP$TELNETSYM_SUPPRESS_FORMFEEDS" = "34"
"TCPIP$TELNET_NO_REM_ID" = "TRUE"

Delta:
(LNM$SYSTEM_TABLE)

"TCPIP$TELNETSYM_ENABLE" = ".1.."
"TCPIP$TELNETSYM_IDLE_TIMEOUT" = "0 00:00:10.00"
"TCPIP$TELNETSYM_RETRY_INTERVAL" = "0 00:00:30.00"
"TCPIP$TELNETSYM_SUPPRESS_FORMFEEDS" = "34"
"TCPIP$TELNET_ENABLE" = ".1.."
"TCPIP$TELNET_NO_REM_ID" = "TRUE"

[Jan van den Ende]

Robert,

your TCPIP$TELNETSYM_SUPPRESS_FORMFEEDS specifies "34", so I would _EXPECT_ you to get the foemfeeds, but, on _BOTH_ systems.
So I think you WILL get rid of your undesired formfeeds by adjusting the value (remember to re-start your queues!),

but, the question remains; "Why the difference between the versions?????"
