Function Documentation

void gp3closeport (    )

Close the GP3 port. Definition at line 60 of file gp3cygwin.c. Referenced by main().

int gp3openport (  char *    port )

Open the GP3 serial port. Parameters: port  The name of the port (varies by platform, e.g., COM1, /dev/cua0, etc.) Returns: -1 for error Definition at line 36 of file gp3cygwin.c. References BAUDRATE.

unsigned int gp3read (  void    )

Read a byte from the GP3. This function blocks until a byte is received Returns: Character or -1 in case of error Definition at line 76 of file gp3cygwin.c. References DEBUG. Referenced by gp3check(), gp3getpins(), gp3gettris(), gp3input(), gp3readee(), and gp3readword().

int gp3ready (  void    )

Optional function reads the CTS input to determine if the GP3 is ready. None of the functions use this (although the demo program does). Using this function it is possible to avoid calling gp3write when it would cause the program to block. Returns: 1 if GP3 is ready; 0 otherwise Definition at line 95 of file gp3cygwin.c. Referenced by gp3write(), and main().

int gp3write (  int    byte )

Write a byte to the GP3. This function blocks if the GP3 is not ready. Parameters: byte  The byte to write Returns: 1 for success Definition at line 67 of file gp3cygwin.c. References DEBUG.
