Because virtual machines running CMS require CONMODE 3215 (but you don't say if you run the command from the CMS Ready prompt).

TERM CONMODE 3270 is useful to run guests.? The CMS abend isn't nice.? So to avoid that
  • All manual:
    SYSTEM RESET? ? to kill CMS
    TERM CONMODE 3270
    IPL xxxx
  • At the console on 1 command
    #CP TERM CONMODE 3270#IPL xxxx
  • In a REXX exec
    nl='15'x
    address command 'CP TERM CONMODE 3270' || nl || 'IPL xxxx'
Often a DEF STOR is done as well before starting the guest: insert that before the IPL command

Thank you for answer.
CMS require 3215 conmode, but programs for 3270 work, it confused me.
 

Thank you,
your answer helped me understand how it works.
 

Strange indeed that 3270 programs work.? But that's an addition not available in the beginning.
CMS only speaks linemode, 3215.
But, CMS programs can use 3270 full screen since VM got "DIAGNOSE 58".? A CP feature for CMS.? Editors like EDGAR and XEDIT? use it; just like FLIST and BROWSE to name things common in VM/SP.
The old, public area CP doesn't have DIAG58 support, but "the community" added this to CP too, and now there is a full screen editor too: EE
?
P.S. when I say CMS has no full screen support, I lie a bit: I think that in VM/SP Rel 5 CMS got it, with VSCREENs and WINDOWs? so you can make your own in REXX for example.? And there can the command SET FULLSCREEN ON to make CMS itself use VSCREENs and WINDOWs, with scrolling features etc.? SET FULLSCREEN ON isn't used a lot.?
Some of my tools on VM's download library ( ) include my SELFS EXEC (Select Fullscreen) and/or RxMB (Rexx MessageBox) to use VSCREENs and WINDOWs. (I can send them to you if you like).? The native use of VSCREENs and WINDOWs isn't that easy.
