Hi to all:

I'm just getting back into this stuff.  I built and got working a
68HC11 board.  I have two processors:  a 68hc11A1FN and the 68HC11E2F

I downloaded PCBUG11A and still can't get the thing to start.

When I put the logic probe on TX and RX on my DB-9 cable, it pulses
(without the cable being connected to the 68hc11 board).

What I touch the reset button on the board, TXD pulses from high to
low to high. RX does not change.  
This is frustrating, as I had the board working before with the same
PC.  I just forgot what I did to get it working.

Any ideas?  What should I follow PCBUG11A with to download the correct
talker  for the 68hc11A1FN?
What baud rate, parity, stop bits, and control should I have this set
to?  The comm ship on the board is a SIPEX 232ACP.  That and the
processor are about the only thing on the board.  I've checked the
power supply.  It's 5.08 at the processor.  
Thanks for the help,

Art

I'm getting a runtime error while using PCBUG11A:

Runtime error 200 at 20FF:0091

Thanks for the help,

Congratulations, your latest PC is now too fast for this ancient
program written in Borland/Turbo Pascal.  Google for "runtime error
200 delay bug" will tell you the rest of this story, and point to
solutions.

Even if all the snow were burnt, ashes would remain.

Downloaded a couple patch files from the sites, but still wouldn't
work. 
I saw a post that someone mentioned disabling CPU cache, but I can't
seem to do that through my HP 523n bios.

Any other thoughts?

Thanks,

Art

I would recomend giving noice11 a go.

It will cost you, but unless you are running plain MSDOS it is a pain
to do RS-232 with windows.

I've tried just about everything, and can't seem to patch pcbug to get
it to work.
Any other suggestions?

Thanks much,

Art

My *nix-based DB11 might be an option for you. The Windows
port is incomplete, but if you need it, I can tell you where
to look - I did intend (and start) to port it.

Hi Clifford:

I'll take any help that I can get.

By the way, I'm running the HP Pavillion 523N AMD 2200.

When I reboot the PC, it sends a pulse on comm1 and sends the 68hc11
into the program that is in eeprom.  I can tell, as the last time I
worked with it on my old computer, I wrote a little program to pulse
an led on the board.  When I run PCBUG11A or other versions of
PCBUG11, I can't see a pulse with my logic probe, and I've gone into
the device manager and monkeyed around with the COMM 1 settings, baud
rate, you name it..Even though it is suppose to be "too fast" for
pcbug, it would seem to me that I would at least see a pulse when I
ran the program.

What is *nix-based DB11?  I'll take it...Could you give me a little
assistance with it?

Thanks,

Art

I can't help with PCBUG11, I've never used it. But DB11
is a command-line equivalent that I wrote, which works
on Unix, Linux, etc (hence *nix). Find the source code
at <http://polyplex.org/cjh/electronics/db11.html>;.
