4716.0. "PC COM1 port as console terminal for a VAX" by UTRUST::TIMMER (Semper TECO!) Tue Feb 11 1997 01:03

    
    I have my COM1 port connected to the console of my VAXstation 3100/76
    (without VRT, so it's really a MicroVAX 3100/76) and that works fine
    as long as I just use DOS with SmartTerm-240 to connect to it.
    But as soon as I start Windows there seems to be a break generated
    on COM1, which causes the VAX to reboot...
    Is there any way I can prevent this?
    
    Rien.

  What about using VTSTAR terminal emulator under Windows? So you have your VAX
  station console neatly as a window on your PC!

But how will that prevent the Break signal (apparently generated whenever
Windows starts) from being sent?

    Right.
    
4716.4probably it is your COMM driver doing you inNETCAD::ROLKEThe FDDI Genome ProjectThu Feb 13 1997 13:364
You may want to try a replacement for COMM.DRV.  See NOTED::MSWINDOWS
note 201.56 for a CYBERCOM.DRV

    Eh... we're in that conference, and there ain't no note 201.56.
    I've searched the entire conference for CYBERCOM.DRV but, no joy.
    
    Rien.

Uh, oh.  I'm losing my noteSkill!

Try NOTED::IBMPC-95 201.56 to see the file.

I can't find any list of switches to comm.drv although a hex dump of
the file shows the word "break" in clear text.  Maybe there is a 
/nobreak switch, maybe not.

Would it be possible to just disconnect the VAX console during windows
boots?
