Apart from that, of course!

 

Actually, I was thinking of some way of getting the device ID from the device manager, in the case where you have lots of COM ports open (eg serial mouse).

Hi Martin,

You can create a panel which asks the user which COM they wish to use.  The address is 1,2,3… for COM1,COM2,COM3…

I don’t know of an easy way of checking to see which COM port has your device automatically from Vee.

The COM port is assigned to a device by Windows in the device manager (Control panel->system->’hardware’ tab->device manager), so you will have to look there to find out which COM port is assigned.  You can also change the COM port here under right-click->properties.

You will need to let Vee see the COM port also, by using the Agilent connection expert.

Hi Dave,

thank you for the hint, but my next question is, how can I get the address?

Hi Martin,

There is a control input on the Direct IO for serial ports, called ‘address’. This will do what you want.  The only difficulty I have found is if you wish to check the buffer contents before doing a read.  For this, you need the ‘Interface event’ box which annoyingly cannot be dynamically assigned a different serial port.  I just created a huge if/then/else function to cater for all the possible serial ports.

Hi VEE users,

how can I change the serial COM port while runtime?

The user from the program should have the possibility to

change the COM port.

Thank you for any hints.
Martin
