[Simh] vax tape Operator input on VMS

[Lu, Mark]

when i try to VAX-VMS5.5-2 BACKUP, i get the following message:

$ backup/image dua0: mua0:tq0.sav
%MOUNT-I-MOUNTED, TQ0 mounted on _MUA0:
%BACKUP-W-MOUNTERR, volume 1 on _MUA0 was not mounted because
 its label does not match the one requested
%BACKUP-I-OPERASSIST, operator assistance has been requested
%%%%%%%%%%%  OPCOM  27-OCT-2004 08:39:19.66  %%%%%%%%%%%
Request 1, from user SYSTEM
%BACKUP-W-MOUNTERR, volume 1 on _MUA0 was not mounted because
 its label does not match the one requested
 specify option (QUIT, NEW tape or OVERWRITE tape)

But then it just hangs there, and i cannot input the "QUIT, NEW tape or OVERWRITE" options.  (but i can ctrl-c).  Is there some "terminal" setup i am missing?

i was trying to use MUA0: attached to a blank tq0.tap file.
Here's my vax.ini for my linux simh:

load -r /vax/data/ka655.bin

attach nvr /vax/data/nvram.bin
;

set rq0 ra92
set rq1 ra92
set rq2 ra92
set rq3 cdrom
;

attach rq0 /vax/data/d0.dsk
