Copy paste in ssh not working for me

I am connecting to pidpi8 via ssh running from a Mac window.

I have tried to copy and paste text from another window to the pidp8i screen (where I have set up a .R PIP / MYFILE<TTY: to save the paste to an OS/8 file) but I am finding either the paste has no effect, or I can paste an initial small block of text and then it locks up.

What's the problem?

The problem is that there's no flow control, and the PDP-8 hardware has no buffering.
When you fill the buffer that the TTY driver is managing and handing that data to PIP, then there's nothing to do any kind of flow control to stop the input while PIP is sending that data to the hard drive.
SIMH could handle this gracefully, but it would then be acting differently from the "real" hardware.

Use the paper tape reader - that has a start/stop that allows the data to be read in until the buffer fills, read pauses and doesn't resume until it's ready to read again.

That, or any of several other methods. You aren't the first person to run into this problem, Andrew. That's why we have documentation. Hint. :)
