On Win2k I have the serial output of a piece of equipment equipment
connected to Com1 and amd trying to read it via the serial control,
but I seem not to be getting anything. It's been about 15 years
since I played with thins kind of stuff so I may be missibg
something.
I've got the instrument and serial port configured the same way witj
regard to baud rate, DataBits, parity and FlowControl as far as I
can tell. Until I matched them teh instrument woudl not send data
and it does now... But I don't get anything from the serial control.
In Window open:
Serial1.SerialPort=System.SerialPort(0)
MsgBox Serial1.SerialPort.Name ' Shows COM1
If Not Serial1.Open Then MsgBox "Can't Open Port" ' does not come up
In Event Serial1.DataAvailable:
EditField1.Text=EditField1.Text+ Me.ReadAll()
In Event Serial1.Error
MsgBox "error: " +Str( me.LastErrorCode)
When I transmit data from the insrument (it says it sent 15 lines)
nothing shows up in the editfield but neither does the error event
fires
BTW same thing happens in Hyperterm when I set the port parematers
the same way...
What am I missing?
Thanks

Maybe check that you don't need a null modem cable, or that the
device is expecting the handshake lines to be a certain state? A
breakout box can be invaluable in order to see that a device is
actually sending, by looking at the LEDs (also that your handshake
lines are correct).
