For my SunOS VMs, I redirect the serial console on the VM to an IPv4 Socket with :
I can then telnet to the serial console (telnet <VMHOST-IP> 10023) and don't need to worry about the speed etc.
SunOS looks for a graphic device and if it is not found, it will then treat the first serial port as a serial console.
What you need to do will depend on your OS and how it directs to
the serial port, but the appropriate variation on the -serial
option for your guest OS should work.

To achieve that goal I have two problems to solve: 1) to have an emulation without a graphic card and a serial console running at 115200 baudTo solve the point 1, one should probably use the instruction «qemu -nographic ...»Yes.My second problem is how to use a terminal program (kermit, putty or cu) to communicate with the serial port of the emulated machine.If you are using xterm or equivalent to start qemu, then you'll have the serial console output redirected to the terminal and you don't need any external software. It's not clear what OS you're running on the host and the guest. The guest needs to be instructed to redirect output to serial console, not vga.
