Greetings,
I have been playing with my recently acquired PDP11/04 (BA11-L) and restoration has been going quite well (anybody who needs hints on how to convert a H777-CA/115V to a H777-CB/240V, please give me a ping).
The console device is a DL11-W/M7856 which came with a 20mA (orginal console was a TTY), which I don't have. BTW, the bootstrap device is M7312. Therefore, I proceeded to make my own EIA cable from the DL11 manual so that I can use my VT320. I made a standard null modem configuration (BERG-DB25F) and made the necessary 9600/8N1 jumper changes to the DL11-W...
The result is that I can get into the console emulator no problem and get the "_at_" prompt. But the problem is that the console doesn't seem to recognize any of my inputs; i.e. I can simply type anything and it doesn't response.
I seem to be receiving data fine, but looks like whatever I transmit from my VT the DL11 doesn't seem to grok/respond.
Any clues?
Thanks.
