Hi, Mike.
My own perception (of course, I can be wrong ;-) )
SYSC emules something like a 3215, not a 3270. When opened, SYSG emules a
3270.
Depending of definitions on SYSTEM CONFIG, VM needs to send a 3270
screen, not possible on SYSC. Generate some Wait code, as the 1010.
Example: IPL xxx LOADPARM SYSC will never be possible, SALIPL needs a
3270 screen.
If the reply don't need a screen, only one line, the SYSC can be used, and
the ipl continues.
Regards,

Hi,
This thread has brought up a question in my mind (maybe it's a dumb one,
but I'll ask it anyway :))
Assumptions:
1) This is the default value for Operator_Consoles in the SYSTEM CONFIG
file (and probably most shops do not delete or change the last two
entries):
Operator_Consoles 0020 0021 0022 0023 0E20 0E21 1020 ,
System_3270 System_Console
2) System_3270 == the Integrated 3270 console == the mnemonic "SYSG"
3) System_Console == the Operating System Messages window == the mnemonic
"SYSC"
As I understand it, the Operating System Messages window is always
available to each LPAR. So if it is in most "path"s for z/VM to find a
console, why should we ever see PSWs of 1010? Shouldn't z/VM always find
the Operating System Messages window as a last resort? (I must have one of
my assumptions wrong, because we do see "1010"s).
Thanks.
