<DIV><FONT face=Arial size=2>All serial ports are not equal... many laptops do
not use the full + / - 12v swing (often only 0 to +5V) of the specification and
that can cause problems. I'm not sure of the particular situation with the TT4,
but back when I used a 'Digital Equipment' laptop with the origianl TT I used a
'buffer' constructed by back to backing a 1488 and 1489 (remembering that each
stage is actually an inverter, you need to feed a reciever into a transmitter
for both the TX and RX lines, but in the oposite direction). You could try a
MAX232 or similar.</FONT></DIV>

<TD vAlign=top>Ron,<BR>I haven't had the problem with the TT4, as I'm
not quite up to your stage yet.<BR><BR>But I have had the same trouble
with the TT3 Plus Congf file on a laptop PC. The only thing I
could put it down to is the XP on the laptop PC, I was using has a 'bug'
or 'problem' in the software some where and it manifests it like this.
<BR><BR>What caused me to think this was a friend had no trouble with
the same XP and laptop PC brand, so I got hold of another older laptop
'Toshiba' set things up and ......... never looked like being a problem,
worked every time,,,,<BR><BR>So I would suggest, set up another PC and
give it go! Old saying "no cheek no fruitcake....."<BR><BR><SPAN
style="FONT-STYLE: italic">When it comes time to run the my TT4, I hope
all will be OK, has been so far with the TT4 software. I have the TT4
Desplay as well but want to understand the TT4 before bringing them
together.</SPAN><BR><BR>All the best<BR>

<DIV><FONT face=Arial>Wonder if anyone in Melbournes Eastern suburbs

<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I seem to be having a bit of a problem with my
Windows box and although I seem to have sorted out and installed the
Alpha firmware, every time I go to the config file and look for a port
it tells me that the TT 4 is not found. I have looked in device
manager and it tells me that the TT 4 port ( 5 ) is working properly
but no matter what I do I just cannot seem to configure the TT
4.</FONT></DIV>

<DIV><FONT face=Arial>Just looking for someone who has " been there,
