You might want to try out my Serial test stack - available from my web page at
<http://www.troz.net/Rev/>
I have just updated it so that it allows you to select termination characters i.e. whether sends should end with CR (ASCII 13), LF (ASCII 10) or CRLF and the same for receives.
Although not of interest to you, it now also works with OS X, but only for Rev 2.1
I think it will solve your reading problem, because it doesn't do a single read, but reads continuously as long as the port is open, reporting whenever it gets any data. One other thought: you probably have to send a command to the milling machine first, to tell it to send it's data and which data to send.

Hi List,
my dad asked me if I could build an app. that stores the Programs of his CNC
milling machine on his Windows PC. I promised him to try it.
The Machine is connected with the computer on com1 and seems to be sending
plain text.
So I walked through the Dictionary and set up the following:
I set the serialControlString to:
baud=300 parity=E data=7 stop=1
(Looking at the old DOS program he has, thats what the machine needs)
I created a button:
on mouseUp put empty into fld "fehler" open file "COM1:" for read put "opened"&cr into fld "log" read from file "COM1:" until end put "reading done"&cr after fld "log" put the result into fld "Fehler" put it into fld "Ausgabe" close file "COM1:" put "closed"&cr after fld "log" end mouseUp
When I hit the button, it instantly reports EOF in fld "fehler".
How do I tell Revolution to wait until the data is sent by the CNC milling
machine? Can I set a timeout somehow to wait let�s say for about 2 minutes?
Any help is greatly apreciated!
Regards,
Malte
