I recently received some barcode scanners that plug directly into a serial port, such as tty/b01. I read that I can disable getty, make a node and open the tty as an input file, but I don't know how to identify the file/pointer/??? to open the file. Can anyone help with a simple C language program? thanks

I got this one from a consultant...when ready directly from a port for a barcode scanner/decoder, simply fopen the device name, such as ttyb16, but remember to fopen in the "rb" mode. "b" denotes binary. Use stty to set the speed and parameters of the port.
