Constants for managing ports List of constants used by the functions for port management (serial and parallel ports) Managing ports (serial ports, parallel ports, USB ports, etc.) Several devices can be managed directly via a management of the ports used by these devices to communicate with the computer... sClose (Function) Closes the specified serial port, parallel port or infrared port. sEndEvent (Function) Disables the detection of an event on a serial port. Serial and parallel port management functions List of functions for managing serial and parallel ports sEscape (Function) Runs different functions that directly affect the bits of serial port, parallel port or infrared port, independently of the communication protocol. sEvent (Function) Branches an event on a serial port. sInEntryQueue (Function) Retrieves the number of pending bytes in the input buffer of a specified serial port or infrared port. sInExitQueue (Function) Retrieves the number of bytes waiting to be transferred in the output buffer of the specified serial port or parallel port. sListPort (Function) Returns the list of serial and parallel ports on the computer. sOpen (Example) Usage example of the sOpen function sOpen (Function) Opens and initializes: a serial port. a parallel port. an infrared port. sParameter (Function) Defines or modifies the parameters for configuring the specified serial port, parallel port or infrared port. sRead (Function) Reads a character string in the entry buffer of the specified serial port. sWrite (Function) Writes a character string to the output buffer of the specified serial port, parallel port or infrared port.
