Note that this does not stop the Send Telnet Control Functions menu from
showing up -- it does though give you control when the user selects option
1 (Interrupt Process - IP).  There is a different exit point for the
Attention key but that unfortunately doesn't block access to the menu due
to the current telnet implementation.

Very cool!  I've been looking for a way to block access to the Interrupt
Process - IP menu item and/or the Send Telnet Function menu for quite
awhile
now.   Thanks for the heads-up on this.

A quick test on a V5R2 telnet target system shows that the Presystem
Request
Exit Program (when specified on the target system) gets control in the
Telnet Interrupt Process scenario and can block access to System Request.

Revoking rights works in MOST situations. However, if you allow the user to
Telnet to another AS/400,  then if they press the attention key, they will
see a Send Telent Function menu, which has an option, "Interrupt Process -
IP" which, when taken, allows access to all that stuff again. This works
even when you specify ATNPGM(*NONE) at both the user profile and System
Value level.  I guess because this funtion is part of the Telnet protocol
and not necessarily OS/400.  I don't know if Bruce's solution of using the
APIs will also address this or not.

you essentially revoke their rights to the sys-request screen...I'll bet
it's in the archives here.
