<DIV><FONT face=Arial size=2>Hi all,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am thinking about writing myself an epos system
for my wonderful book shop.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I would, of course, like to produce some
oss.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>
<DIV><FONT face=Arial size=2>I am thinking that it would need:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>1. gui app for the till interface
(QT?)</FONT></DIV>
<DIV><FONT face=Arial size=2>2. database (postgreSQL?)</FONT></DIV>
<DIV><FONT face=Arial size=2>3. middle tier module for controling the cash
drawer (???)</FONT></DIV>
<DIV><FONT face=Arial size=2>4. report producing module for end of day totals
etc (???)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I would like to leave the system open enough to be
able to write modular 'plugin' components for such things as 'customer orders'
etc.</FONT></DIV></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>My first requirement will be to be able to
control (open and shut) a cash register type drawer. I have seen pictures
of these things which are like cash registers without the cash register
:). In effect they are just the drawer with the money in it.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I want to be able to open and shut a cash drawer
from my app. </FONT><FONT face=Arial size=2>I have no experience of anything
like this. I assume it would probably communicate via a serial port?
</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Is there any one with experience of programming for
this kind of equipment on the list???</FONT></DIV>
<DIV><FONT face=Arial size=2>Even better, does anyone know of one of these cash
drawer thingies for sale???</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have seen _one_ of these for sale.
Here is a link to the manual for the one I have seen. Does this seem
usable? Should someone of my beginner status with serial port programming
attempt such things?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Cheers,</FONT></DIV>
