The Question is: I am trying to attach a Wyse 50 terminal to VAXstation 3900 (VAXstation II/GPX w/KA-655). The terminal controller board is a OEM DHV11 (Camintonn CM-DHV11-C). I can connect the Wyse 50 to the OPA0 port and it talks to the VAX, so I know it's a good termi nal. When I connect it into the DHV11 port (TXA0) there appears to be no communication. Leaving the Wyse 50 connected to TXA0, and logging into DECwindows and try a "reply /term=txa0 "hi" and all I see appear on the Wyse are what appear to be carriage r eturns. All the documentation that I have looked at implys that plugging in the terminal, and setting the terminal characteristics are all thats required. If this isn't known problem, ideas were to go look would be helpful The Answer is : Please contact Camintonn support and/or Wyse support for assistance. What recently changed in this configuration? Is this simply a new terminal and other terminals work fine, or is the Camintonn serial line controller newly installed, or both? Under supported OpenVMS terminal controllers, the serial lines must be set to compatible characteristics (bits per character, stop bits, etc) with the terminal, and to a compatible speed or autobaud detection must be enabled. Also ensure that all controllers in the Q-bus have the correct CSR and interrupt vector setting -- the CSR is likely correct on the Camintonn controller, as the device is apparently visible to OpenVMS. The device interrupt vector on this or other controllers in the Q-bus, as well as the CSRs of other devices installed in the Q-bus could still be incorrect. Please see Q-bus discussions around the word "serpentine" here in Ask The Wizard area (eg: topic (1149)) and in the OpenVMS FAQ. VAXstation systems were typically licensed as single-user systems.
