I am in the middle of doing a project in Perl and am wondering if anyone has used the Device::SerialPort module for something other than modems? To be specific, I am trying to interface OMR Scanners with Perl. I was wondering if anyone had any examples of this, or even examples of reading back from serial port interfaces. I can open the port, write to it, but upon trying to read back, nothing comes up. I would appreciate any input. Thank you in advance.
