All new GSM sticks are USB today

[abak]

Hello Roman Novgorodov,

As far as i know, GSM are recognized from Port COM  -->  Delphi GSMDemo

Is there a way to detect sticks GSM from USB ?
Is it so difficult ?

i baught a stick GSM (USB) D-Link DWR-910M and has no COM driver.

Thx

Hello

You can take a look USBDevice Demo. It shows all available usb devices and can get its descriptors.
Also you can see SerialPortInfo demo. It shows some details about serial port.

Now about DWR-910.

Possible it does not provides GSM AT specification at all and it works as an virtual network adapter (like Ethernet or VPN). In this case the nrComm Lib TnrGsm solution will not help you. Sorry :-(

But possible you need find and install the correct (or special) system driver for DWR-910 that provides virtual serial port. In this case GSM functionality will work.

I see that DWR-910 provides Web interface with various options. Maybe you need to find something like "Enable virtial (serial,com) port or interface" in it.

Maybe we will try purchase DWR-910 in the future and test it.

Hello Roman Novgorodov,

As a challenge this year,
Can you please develop and add an :

*** USB port communication for GSM ***

So, From the demo gsm we could select :
- Com1
- Com2
- ...
- USB1
- USB2

This will save us many times, as major computers come today without port Com.

Thx
