<div>Dave, </div><div><br></div><div>Thanks, I was able to file out SerialPort from Squeak into Cuis. I tried this code in a workspace:</div><div><br></div><div><div>| port oc |</div><div>port := (SerialPort new) openPort: 'COM4'.</div>
<div>oc := OrderedCollection new.</div><div>port nextPutAll: '>01100'.</div><div>oc add: port readString.</div><div>oc add: port readString.</div><div>oc add: port readString.</div><div>port close.</div><div>oc </div>
</div><div><br></div><div>Some data was sent out as indicated by an LED at the connection. Unfortunately, the response was empty strings which is incorrect based on the off shelf software. I tried adjusting the baud rate but that did not help. Any suggestions? Thank you.</div>
<div><br></div><div>Also, I'm interested in hooking the serial port code up to an application window like the original. Can you please point me to a tutorial to learn how? Eventually I want to migrate from simple text response to tables or graphs.</div>
<div><br></div><div>------------------</div><div><br></div><div>jinoh67, </div><div><br></div><div>> "To access IO device, use FFI" </div><div>sounds like good advice but without more details I can't do it. Can you refer me to a tutorial on using FFI?</div>
<div><br></div><div>Thanks,</div><div>Kirk Fraser</div>
