SERIAL_Open

Gets a weak ownership of the port. Subsequent calls to this function with the same parameter will fail unless SERIAL_Close() is called for the same port.

Synopsis

int SERIAL_Open( int port );

Parameter	Description
port	Serial port number (0 based). Specify port 0 to redirect the output to the hsmtrace log.

Return Code

0: Port opened successfully

others: An error prevented the serial port from opening

Comments

This function in no way guarantees safe sharing of the ports.

Any application can call SERIAL_Close() to get the access to the port, or can use SERIAL functions without opening the port first.
