Answering my own question, it looks like you can give multiple commands as the argument to "expect", so
set BDR 80 expect ">>>" send "BOOT DUA0\r"; continue boot cpu will work as expected. Should have read the manual J Bob From: Simh [mailto:simh-boun...@trailing-edge.com] On Behalf Of Robert Armstrong Sent: Wednesday, February 26, 2020 10:25 AM To: simh@trailing-edge.com Subject: [Simh] MIcroVAX-3900 Autoboot problems revisited ... There's a problem with the MicroVAX-3900 in that sometimes the ROM built in self test fails with ?53. That's not terrible, but it prevents the VAX from autobooting, which can be a problem if you're running a script that expects to start VMS. Mark suggested doing something like this in the script - set BDR 80 (disable auto boot) expect ">>>" send "BOOT DUA0\r" boot cpu That's OK, but I'm having a problem now. The issue is that "boot cpu" waits until the simulation ends (i.e. until VMS is shut down), but somehow the "expect" is cancelling that wait. If I use the "expect" then the commands in the simh script after "boot cpu" get executed immediately, rather than waiting until after VMS shuts down. That's bad (at least for me!). Is there a way around this? Thanks, Bob Armstrong
