Comunication COM1: and a CNC milling machine (timeout?)

[Sarah]

Hi Malte,

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.

Cheers,
Sarah
