Two problems

[Christer Karlsson]

I am sure this has been answered several times, but I can't find it.

1) When booting the Raspberry Pi it starts in graphics mode, not in terminal, how to change that?

2) I am unable to get it to communicate using PL2303. Do I need to make any changes to the defaults in the Raspberry Pi?

The key is you need to think in terms of the RPi before you think about the PiPD-8/10/11

Internet search is your friend (look up raspberry pi  serial boot)

1) When booting the Raspberry Pi it starts in graphics mode, not in terminal, how to change that?

But since I know how to do by memory, I'll save you a little 

• Put the RPi SD card iInto a computer that can read the FS on it
• In the root/boot directory edit the config.txt [use a real tex edit like vi/emacs not MSWord]
• Append: enable_uart=1 to the end of the file and save it
• Remove the SD card, and put the card back into the Pi and attach a serial console/you local computer via an RS-232 port
• set the baud rate to 115200
  
• On the local system, using a program like Mac's Serial, Windows Putty of Linux "minicom" connect to the local systems computer port
• power the RPi and you should be good

Thank you! I start to understand this better!

In a terminal do

sudo raspi-config

and choose 

system options

-  Boot / Auto login
   - Console auto login

Next time you boot and remote login with e.g putty you will be welcomed in the PDP-11 console.

I mean PDP-8 of course, but the same config applies to the PiDP-11
