SERIAL_Open
Gets a weak ownership of the port. Subsequent calls to this function with the same parameter will fail unless SERIAL_ClosePort() is called for the same port.
Synopsis
#include <serial.h> int SERIAL_Open( int port );
Parameters
| port | Serial port number (0 based). Specify port 0 to redirect the output to the HSM trace log |
Return Code
| Function Code | Qualification |
|---|---|
| 0 | Port opened successfully. |
| -1 | An error prevented the serial port from opening. |
Comments
CAUTION! This function in no way guarantees safe sharing of the ports. Any application can call SERIAL_Close() to get the access, or can use SERIAL functions without opening the port first.
