Changing console from serial to graphics on AS800 from VMS?

by sampsa＠mac.com

Is it possible to change the OPA0: (on reboot, so it sticks) from serial to graphics on an AS800 through VMS? Sampsa

DECnet performance problems (on TOPS-10)

by ahling＠eadc.se

Sorry for not being "expertly experienced on tops-10" (I know others who are... ;-) On PDP:s (RSX11-Mplus) and VAX/VMS, C-TERM (eg. SET HOST) is usually sort of "sluggy". LAT (eg SET TERM/LAT) is a protocol developed to cope with terminals character by character communication at first hand! I don't know if LAT is available to your 10-system, though, but if it is, use that for terminal traffic as far as possible. Besides, what version of VMS, on what hardware? I've heard birds singing of problems combining modern VMS-DECnet with older implementations in other machines...

Anyone with a spare MMJ cable + RS232 adapter?

by sampsa＠mac.com

Those would be very welcome as well, esp the ones that are wired to a DB9-F on the other end.

DECnet performance problems (on TOPS-10)

The paramters you posted are aal defaults except for the node name aand address, right? Two suggestions: - have a look at the exec, line and circuit counters - examine the host IP characteristics and (if present) those of the winpcap package installed on the host Hans Verzonden vanaf mijn draadloze BlackBerry -toestel -----Original Message----- From: gerry77 at mail.com Sender: owner-hecnet at Update.UU.SE Date: Wed, 31 Aug 2011 02:20:37 To: HECnet<hecnet at Update.UU.SE> Reply-To: hecnet at Update.UU.SESubject: [HECnet] DECnet performance problems (on TOPS-10) Dear All, I'm in need of some suggestions to improve DECnet performance of a TOPS-10 monitor running on KLH10.

Are 3 wire sufficient? Most of the ones I make, I only end up doing RX, TX, and GND, but I can do the handshaking lines if you want. The cable I have most of is 6 wire, but it's solid conductor, like telephone wire. Works well enough for these speeds/installations, though. To be clear, let's agree on the cable specs: MMJ - MMJ RX, TX, GND 6' (2m) long enough? Qty 4 As for $$, I find your suggestion ambiguous. (If you sent me 5Eu and told me to spend it on a 30Eu bottle of wine, it would fit.) So how about $25 Canadian + postage? Before we get too excited, I'd better locate the connectors. Will confirm. Cheers, Phil

My server is not apparently getting along with the HECnet list. I have a couple of dozen MMJ connectors in the shop, I believe. I could send you some, or we can talk about making up a cable. (I'd rather not be without my MMJ crimping tool.) Best, Phil

Noob question: Changing the Time Zone on my VMS boxes?

Yes, There is a script given: $ SYNCH_CLOCKS: $ RUN SYS$SYSTEM:SYSMAN $ SET ENVIRONMENT/CLUSTER $ CONFIGURATION SET TIME $ EXIT $ WAIT 6:00:00 $ GOTO SYNCH_CLOCKS Seems like a sensible thing to do in a clustered environment.
