zero-tolerance

I have attached the code of what I have done so far. Im new to the LabView hence even though the solution might be simple i cant figure it out, otherwise i wouldn't be posting for help for such a simple problem. Anyway I have explained of what the problem is above and if anyone cares to have a look and help me out here i would appriciate it. thankx in advanced. Download File:post-4068-1139758233.vi

Another problem that i am facing with LV is when I recieve the message on the screen the old message does not get replaced with the new one. E.g. when I reset my hardware a message comes on giving about 3 choices to the user and when the user enters the desired choice it goes to another menu, but LV does not replace the old message or the old menu. is it possible to do this or have you allready got an exammple that you can shown me. It'll be really hellpfull, thnx.

I have actually gone through them allready. I've spent a whole day trying to find the problem but i couldnt see anything apperant. The one thing is bothering me is that when I run it through Hyperterminal I cannot see what i'm writing but its there in a invincible mode, and as soon as I pres [ENTER] the commands go through and I get the right response from the motor. But through Labview I cant see anything reply at all, whereas when I talk with the same LV program to my own Hardware device I can actually see read what comming and everything.

Hi everyone, i am trying to send a string of characters "01OS" and "01RS" through the serial interface to a device called PM301. when i connect the device to the serial port without even sending anything i start getting rubish readings on LabView but when i connect it through the Hyperterminal then I dont get any of those readings. what i should really have in return from the device is "01#ok" no matter which one of the above commands I sent but i dont get that, instead on LabView I am Flooded with some none-sense readings. the device i am talking to only understands characters like the above commands. What i am worried about is if LabView is sending to this device something on the background as soon as I run it i.e. without my knowledge becuase i dont get any of the rubish reading through hyperterminal. the serial port settings are : Baud rate 9600; Data bits 7; Parity: EVEN; and no handshaking is require with the device i.e. the device only has three wires in its serial port, the read pin, the write pin and the ground. anything is welcomed ..... AND Thankyou in advanced
