[snip] Actually, the JBC -DOES- start. However, little-known fact: until a SET LOGINS/INTER=n command is issued at least once, JBC will NOT create interactive processes. THAT is why you can't login if STARTUP bombs out before SYSTARTUP_* completes. This is true for hard-wired terminals, CTERM, LAT and UCX/Telnet. Not sure about SSH - never had a chance to test it. The exception is Telnet in Multinet. For Telnet sessions, the MULTINET_SERVER process is the parent of the interactive Telnet sessions. It WILL allow logins as soon as it starts, and is not aware that STARTUP failed. (Not sure about TCPware - never had a chance to test it.)

But trapping CTRL/C with SMG$SET_OUT_OF_BAND_ASTS does not trap F6 when it is configured to trap CTRL/C. However, you can trap F6 with SYS$QIOW as illustrated here with a handy example program CTRLC.FOR: http://h71000.www7.hp.com/doc/82final/6443/6443pro_049.html This appears to be promising. I tested the example program and it does trap F6 when line editing is enabled for the terminal. ------------------------------ Date: Fri, 17 Oct 2008 17:48:54 +0000 (UTC) From: helbig@astro.multiCLOTHESvax.de (Phillip Helbig---remove CLOTHES to reply) Subject: Re: DS10 front access storage cage (3X-BA10B-AA) Message-ID: <gdaj66$u7u$2@online.de> In article <6qednUqtnYznDWXVnZ2dnUVZ_tudnZ2d@comcast.com>, "Richard B.
