Introduction The SerialDeviceSupport module provides implementations of the legacy [[OS_SerialOp]] SWI and serial-related [[OS_Byte]] calls. However it does not directly talk to the serial hardware; instead it only talks to DeviceFS devices which implement the appropriate serial device protocol. [[SerialDeviceDriver]] and [[DualSerial|Serial / DualSerial]] are the two standard modules which provide devices which implement this protocol. h4.
