|
| By: Alex | Posted on: Jan 31 2013 at 09:11:30 AM | | I open the sample c# project in VS2010. the program can find all the com port. However when I open the oport, the machine crash. Ther is no problem in VB6 using scomm32.Why? | |
| By: Support | Posted on: Jan 31 2013 at 03:20:41 PM | You're using Comm64 ? (The .NetDLL ?) That has it's own dedicated website and support forum at
www.comm64.com
But, in response to you question, Comm32.OCX is an ActiveX OCX but Comm64 is a .Net DLL so they are completely separate modules. What error message do you see when it crashes ? What kind of Com port is it ? | |

I use comm64.dll on vs2010 c#, the port I want to open is a bluetooth comm port
the OS is win7 32bit machine. I use the sample program that comes with the installation. the port found is com port 40. When I try to open the port. The machine crash and a blue screen appear without any error message.I can email the screen capture to u ,but what is your email.Thanks | |

I suspect there's a problem with the device driver.
Are you able to test the port using some other software such as hyper terminal?

| By: Guest | Posted on: Feb 2 2013 at 02:43:07 AM | | yes , I can open the port with VB6 and use scomm32 on the same machine but fail in dot net | |
| By: Support | Posted on: Feb 2 2013 at 10:52:18 PM | Would you use device manager to change the port name to a lower number. Maybe com6 or com7
Com40 ought to work but the result of testing it as a lower numbered might might help me diagnose the problem. | |
| By: Guest | Posted on: Feb 4 2013 at 01:30:44 AM | | The bluetooth port is assigned to com 40 when I installed the driver for the BT doggle and there is no way to change it. I have tried to installed to other PC The port is still the same. I tested the comm64 on usb to comm doggle, it works. May be the driver for the BT doggle works with scomm32 with any port and comm64 is not compatiable to the BT doogle. | |

| By: Guest | Posted on: Feb 25 2013 at 08:42:26 AM | | EagleTec BT dongle made from Taiwan | |
| By: Support | Posted on: Feb 25 2013 at 07:14:40 PM | I tested Comm64 with BT dongle. Paired with my cell phone. Com40. Sent AT commands and got expected response from the cellphone/modem so I'm sure there's no problem with Com40.
I looked at the eagletec website but I cant see which product you're using. Maybe there's more than one 'eagletec'? Can you email a link to the product page so I can see exactly what product you're using.
