Your EXEC is using the SCIF (Secondary Console Input Facility) which lets you 
send and receive commands from a machine that you are set as the SECUSER 
(secondary user).Try passing this command to the boot loader: send cp linuxvm 
vi vmsg 0  
You may have to play with the exec a little.  Your exec as coded only sends 
virtual machine commands to LINUXVM. You need to send a CP console function 
command. SEND CP LINUXVM will send the cp command to linuxvm. vi vmsg will pass 
the command to the boot loader as if it were command from the hardware console.

Subject: 3270 input to zipl boot menu
 
I'm using zipl version 1.3.1 and am unable to send input to the boot
loader via a 3270 terminal emulator.  I'm using the following script to
send input to the VM user:

00001 /*Send case-insensitive commands to linux on LINUXVM*/
00002 Trace Off
00003 Address Command
00004 Parse Arg Command
00005 'EXECIO 0 CP (SKIP STRING SEND LINUXVM' Command
00006 Exit Rc

which works fine once the kernel is up.  I can log in, issue linux
commands, etc.  However, when I'm at the bootloader menu prompt, the
script has no effect and I'm unable to load a non-default kernel or pass
boot parameters.

I'm a complete newbie to the VM world, so I'm not sure what's going on
here.  Does anyone have any ideas?

Thanks,
Brian
