Keystrokes dropped when pasting text

[mike632t]

I think this is related to issue #22.

I started the emulator using

./rc2014 -a -r ./R0000009.BIN -e 0

However when pasting text (e.g PI.BAS) into the emulator most of the 'keystrokes' are dropped, even when pasting a single line of text.

When using a real serial interface I the rate at which keystrokes arrive is limited by the baud rate but when pasting text in a terminal window the input easily overwhelms the emulated serial interface.

Would it be possible to buffer the input (except for ctrl-\) before it reached to emulated serial port, so keystrokes are not dropped?

Thank you.

It's a difficult one with emulation as to what is correct.

if you hack acia.c so that

        /* Already a character waiting so set OVRN */
        if (acia->status & 1)
                acia->status |= 0x20;
        acia->rxchar = acia->dev->get(acia->dev);

instead just returns if status & 1 then I think you'll get the behaviour you want

Made the following change

	if (acia->status & 1)
	{
		return; /* Workaround */
		acia->status |= 0x20;
	}

The result doesn't drop individual characters but there is still an issue when pasting multiple lines.

Does "-f" as an optionc change that ?

[mike632t]

No.

Noticed that it stops accepting input at the same point every time - only the first 64 characters register (including single 'carriadge-returns' at the end if each line).
