In computing, a serial port is a serial communication interface through which information transfers in or out one bit at a time in contrast to a parallel port. I am a little bit confused about reading and writing to a serial port. I have a USB device in Linux that uses the FTDI USB serial device converter driver. When I plug. CI wrote this a long time ago, and just copy and paste the bits needed into each project. CSIZE CS8 8 bit chars. IGNBRK for mismatched speed tests otherwise receive break.

The values for parity are 0 meaning no parity, PARENBPARODD enable parity and use odd, PARENB enable parity and use even, PARENBPARODDCMSPAR mark parity, and PARENBCMSPAR space parity. Blocking sets whether a read on the port waits for the specified number of characters to arrive. Setting no blocking means that a read returns however many characters are available without waiting for more, up to the buffer limit. Addendum CMSPAR is needed only for choosing mark and space parity, which is uncommon. For most applications, it can be omitted. My header file usrincludebitstermios.
