This may sound strange, but I need to know if anyone has written an X11R3 server using UIS graphics under VMS, more specifically for a VaxStation II, monochrome. The main reason we're doing this is that we don't like the way the DecWindows server runs under VMS on these old, clunky machines, and we would like to be able to switch between UIS and X without having to reboot the @%#^$&* system. Please either post replies to this newsgroup, or send email to ccjlund@agl.cc.utexas.edu.

I have an endless respect for your courage. Not only you would have to make the MIT server compile under VMS, but you'd have to hook into VMS-specific transport mechanism, used by VMS flavor of Xlib (local==shared, DECnet, TCP/IP, LAT ...). Plus you can expect about 5 times worse performance. On the other hand, VWS 4.1 includes an option to run DECwindows on the top of VWS(UIS). The DECwindows server gets a UIS window covering the entire screen, and you can run both UIS applications and X. Yes, it's a memory hog, but the performance did not seem to be much worse than the "native" X. The initial version was "unsupported", i.e. buggy and unreliable, but I believe the current status has been upgraded to "supported". In addition, DEC is readying the UIS emulator under DECwindows (demoed at DECUS). I believe they can be done sooner than you - even considering typical VMS Digital has it now (when can I get it -) . -- ############################################################################### Martin Brunecky, Auto-trol Technology Corporation, 12500 North Washington Street, Denver, CO-80241-2404 (303) 252-2499 ncar!ico!auto-trol!marbru
