Hi all,

I am trying to read the serial number from a card reader. I have the MSComm control installed on a form. I am able to read driver's license info from the reader. I am trying to read the device serial number. According to the programming specification, I should be able to do this, but I get nothing back when I send the command. I can tell that I am communicating with the device, because the indicator lights up when I send the command. The programming specification is located at http://www.e-seek.com/pdf/Serial_Programming.pdf.

Here is the code I am sending to the device.
Any help will be greatly appreciated.

lcString=['SOH'<SERIAL:>'EOT']
ThisForm.Olecontrol1.output=lcString
lcx=ThisForm.Olecontrol1.input 
?lcx
