Command for Com Port

Hi,
I'm writing a program for counting bills in VB.net. I'm using L70 of CTS Electronic device for read the bills (OCR scanner) and it's connected over Com Port. I need to find a command to start "read". It can be reprogrammed to read automatically when sensor recognize a bill, but, for a external proprietary software, cannot do that.

Thanks
Manuel

Can the scanner recognize external commands? Your post is not clear.

The device recognize external command because a propietary (closed coded) software have that "button" to start read and it works. I've sended an e-mail to CTS but get no answer. Physically the device don't have any button.

Connect a terminal to your computer and find what the "button" sends.

I've got that from terminal(debug): L50_ScanOCR,II:0zSql::Compile:[
Select fkh_id from TKMn_fakthdr where fkh_skl = @v1]

It's looks like sql command, surly for 2nd line. Dunno how can convert that to VB.net code.
