blade console opa0: nobroadcast

Why does the OPA0: terminal device come up /nobroadcast?  TTY_DEFCHAR is 402657952 = 180012A0(hex) and the NOBRDCST bit is 20000(hex) so I expect the broadcast characteristic to be enabled.  On old VAX and Alpha systems this was not a problem.

 

Yes, it can be manually set after the system is up with $ SET TERMINAL/BROADCAST and $ SET TERMINAL/BROADCAST/PERMANENT but that's nuisance.

Re: blade console opa0: nobroadcast

Hi David,

 

   There's some logic in VMS$DEVICE_STARTUP.COM which includes the lines:

 

$if .not. enable_opa0
$then
$  set terminal/permanent/nobroadcast OPA0:
$endif

 

Maybe you can chase backwards to figure out what enable_opa0 would be on your system. If it's not what you want, try:

 

$ DEFINE/SYSTEM/EXEC OPC$OPA0_ENABLE TRUE

 

in SYLOGICALS.COM

Re: blade console opa0: nobroadcast

Good lead John; it turns out the problem is we have DECwindows configured.
