NETCommOCX Port Check

[Vision]

Hi,

im usin NETCommOCX.NETComm for my COM scripts/tools

works perfect for me but if i try to open a port what exsits but isnt connectet autoit will crash.

here my code snip:

;   >>STARTING NET COMM 
$NetComm = ObjCreate("NETCommOCX.NETComm")
;   >>NET COMM SETTINGS 
With $NetComm
        .CommPort = $portsetting      ;Port 
        .Settings = "9600,N,8,1"      ;Com Settings 
        .InputLen = 0                 ;reads entire buffer
        .InputMode = 0                ;reads in text mode
        .HandShaking = 1              ;uses both RTS and Xon/Xoff handshaking
        .PortOpen = "True"            ;opens specified COM port
EndWith

so the line: .PortOpen = "True" ;opens specified COM port

trys to open it but he cant and then autoit do a crit error

exsample: im using bluetooth, so the Port is there but not active when the usb-stick isnt connected.

when im trying to open the port autoit will crash (just logical cause he cant open the port)

So is there a way to check the port if it is usable before he trys to open it?

sorry for my bad english

Take a look at ObjEvent() that allows you to set up a COM error handler. This allows you to make COM errors non-fatal to your script... you can then trap them and decide for yourself what you want to do.

Even though you are not using IE in your solution, a quick way to test this is by adding the following two lines to your code:

#include <IE.au3>

_IEErrorHandlerRegister()
