Chr(#) to COM8 ?

[LarsBNygaard]

How do I set a script to send i.e. Chr(255) + Chr(1) + Chr(0) to the COM8 port?

I need this, in order to turn a relay connected to CON8 on/off.

Any help will be appreciated!

----------------------------------------------------------------------

Sample VB6 code :

Private Sub cmdOff_Click()

With MSComm8

'make sure the serial port is open

If .PortOpen = False Then .PortOpen = True

'send the data

.Output = Chr$(255)

.Output = Chr$(1)

.Output = Chr$(0)

End With 'MSComm1

End Sub

Private Sub cmdOn_Click()

With MSComm8

'make sure the serial port is open

If .PortOpen = False Then .PortOpen = True

'send the data

.Output = Chr$(255)

.Output = Chr$(1)

.Output = Chr$(1)

End With 'MSComm1

End Sub

martin has a great com.dll UDF in example scripts forum which will more than likely help you.

Yes, you can easily deal with what you have shown using my udf. There's a link in my signature.

Thanks a zillion to John and Martin,

I've downloaded and looked at the example script, and I must say, that here I'm overchallenged...

Would it be possible to talk one of you into writing two sniplets of code for me, one "turn it on" sending Chr(255) + Chr(1) + Chr(1) to COM8 and one "turn it off", sending Chr(255) + Chr(1) + Chr(0) to COM8 in such a manner, that I can set the trigger myself, i.e.

#include <Date.au3>
$Dato=( _NowDate())

-and then set the date as trigger, for sending the chr¤'s to COM8..?

yes

Thanks a zillion, I'll wait in great excitement to see the solution.!

You have misunderstood "yes".

Your question was

"Would it be possible to talk one of you into writing two......"

So "yes" it would be possible, but the chances of succeeding in pursuading me at least are very, very slim.

If you put in some effort and make an attempt at some code then I am happy to help with any problems. But using someone else to think for you is a bad idea IMO. Using someone else so that you can do nothing is just bloody lazy.

There is an example script with the udf, and the udf contain information on all the functions. Then if you look through the thread for the udf you will find examples where people have used the udf to send characters as you want to do. So get your ass into gear.
