Try top put "-serial mon:stdio" before "-serial telnet::4441,server"

Effectively, no more error !
Now, my hppa machine is booted on its installation support for HP-UX 10.20, et I am connected with telnet in an other terminal. I don't know what I must enter now (on a real machine, the installation starts automatically, if I remember well what I did in 1990 !)

If I use an installation support HP-UX 11.00, the installation starts automatically. Then, it finds no disk for installation, but I will work on the drive option of qemu to resolve this trouble.
Thanks a lot for your help !

I would observe that it would be much better if the order of the -serial
arguments did not matter so much. I know gcc has the same sort of
madness (for instance), but it sure isn't intuitive.
But in my case, when you do the -serial things out of order, you end up with a segfault.
That can't be the intended behavior.

Yes, a segfault is definitely a bug. Can you give instructions to
reproduce that (full command line, any necessary images) ? The example
originally reported in this bug doesn't seem to be a segfault.

problem.

Reporting again. Compiled QEMU from the latest stable Git:

Copyright (c) 2003-2021 Fabrice Bellard and the QEMU Project developers
Exactly as original post, if I place -serial telnet::4441,server ahead
of -serial mon,stdio on the command line, it dumps core and aborts.
if I flip them, it runs... BUT! The vm console output appears in the
terminal where I launched qemu, I get no output in the telnet session.
That's backwards. I have no access to the qemu console and can't issue
commands to do things like change the CDROM.
full command startup script (this one works but output doesn't happen
where I expect)
#!/bin/sh

This one dumps core with the serial0 error from the originla post:
