In the course of Work (mutter, mutter) I have come across an oddity I wrote a C# program to communicate via the serial ports which worked fine until a few weeks ago. Some of our boards will now not work with my program so have gone back to try to emmulate HyperTerm which will do the job I have managed to get the out put to appear in real time as it is typed with a Rx Tx short (no click send button for text to be sent as a string) but the board sees the data (a flashing LED will indicate that data is being recieved) but the 12 Volt relay is not switched the input routine I am using is :
private void rtbOutgoing_KeyPress(object sender, KeyPressEventArgs e)
{
if (e.KeyChar == (char)13) // enter key
{
myComPort.Write("\r\n");
Thread.Sleep(200);
tmrPollForRecievedData.Enabled = true;
rtbOutgoing.Text = "";
} else if (e.KeyChar < 32 || e.KeyChar > 126)
{
e.Handled = true; // ignores anything else outside printable ASCII range
} else
{
myComPort.Write(e.KeyChar.ToString());
}
}
This appears to do every thing but the intended to the board I don't want to point fingers and cause my self to look like an idiot if there is a fault at my endbut will this act like Hyper Term?
