I have finally managed to get my test PC to load a iPXE loader and with that I
can boot RTEMS. Without the changes I can run hello.exe and it prints the right
stuff on the monitor however the iPXE boot command line that use to work ...

chain tftp://10.10.5.2/rtems.exe --console=/dev/com1,115200
--printk=/dev/com1,115200

... does not generate any serial output. The output is being redirected and the
serial port because nothing appears on the monitor and I tested the cable is
working with a loop-back jumper.

Is the PC serial port driver broken?
