Hi All,
I plan to emulate with qemu a machine without graphic card
and with only a serial console.
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 baud
2) on the host to be able to interact with the emulation with
a terminal program running at 115200 baud.
To solve the point 1, one should probably use the instruction «qemu -nographic
...»
The problem is that I have found nowhere in the documentation how to force the
speed
of serial port in the emulation to 115200. I haven't even see any mention of
the speed
of the serial port.
My second problem is how to use a terminal program (kermit, putty or cu) to
communicate
with the serial port of the emulated machine. The first pitfall is how to
specify the port where to read/write data. If the machine were
real, «/dev/ttyS0» could be used to transmit data to the serial port, but
I have seen no way to communicated with the serial interface of
the emulated machine neither on Linux nor on Windows host.
Any pointers would be greatly appreciated.
Best regards,
