For a while now, I've successfully used a 65C51 with my SBC. But it was built on a breadboard with wires all over the place.

I've recently built a small plug-in card (think Apple II card) for my SBC for the ACIA and it seems to work with one exception.

Everything is contained on one line in my serial terminal.

It's like line-feeds/CR doesn't work.

I'm using Putty as my serial terminal and I've looked through all of the settings I can find.

I'm 99% sure I have things set at 19200, 8 data bits, 1 stop bit, no parity and no flow control.

The circuit I am using is here:

This is how I had it on my breadboard and it worked.

Any suggestions?

I admit it's been a couple months since I've tinkered with this so I may be missing something stupid.

Thanks.




** EDIT **

Feel free to delete this. I switched to another terminal program (Termite) and it works.
Must be something bizarre with Putty.

Thanks.

Are you outputting both CR (x0D) and LF (x0A) at the end of each line?

If not you'd need to set your terminal program to add the LF after a CR.

Doing so takes away some flexibility, but suits most needs. The default for the new program you are using is probably to force the LF after each CR.

PUTTY tends to be very literal (assumes nothing) and everything needs to be configured.

You're correct. I cannot find in Putty where to insert the LF/CR. In Termite, it's right there in front of you. Once I turned that on, it started working.

Now, I have another issue...which I will start in another thread.

Thanks!
