/***********************************************************************
 *
 * Function:    pilot_connect  [DEPRECATED]
 *
 * Summary:     Connect to a Palm device.
 *
 * Parameters:  port. Communications port through which the Palm device is
 *              connected.
 *
 * Returns:     Socket descriptor of type 'client_sd', if successful.
 *		Returns 1, if the connection can not be established.
 *
 *  'port' is allowed to be NULL for the pi_bind call because pi_bind will
 *  check your PILOTPORT environment variable.  If port is NULL and the
 *  attempt to connect fails for any reason, we simply assume the user didn't
 *  provide one, because pilot_connect doesn't have a way of knowing, for the
 *  time being.
 *
 * This function is deprecated because it doesn't really belong in libpisock.
 * It will remain at least until it has been properly replaced.
 *
