Define Documentation

#define MSG_PRI   210

The priority of the MSG output task.

#define RT_CMD_RECV_NAME   "uCmdRx"

The name of the telecommand receive task (VxWorks only).

#define RT_CMD_RECV_PRI   150

The priority to run the telecommand receive task (VxWorks only).

#define SUMT_RT_TASK_NAME   "uRT"

Function Documentation

int rt_diag (  void   )

Displays remote terminal diagnostics. Return values: 0  Success. -1  Failure.

Here is the call graph for this function:

int rt_exit (  void   )

Stops the test application and releases resources. Return values: 0  Success. -1  Failure.

Here is the call graph for this function:

int rt_init (  void   )

Initializes the target side of the test application. Return values: 0  Success. -1  Failure.

Here is the call graph for this function:

void rt_pkt_cmd_rx (  void   )  [static]

Listens for telecommand receive packets arriving at the remote terminal. The SC broadcast telecommands (APID=0x701) are discarded. The communications test diagnostic telecommands (APID=0x646) are parsed and the appropriate telemetry response actions taken. The rececption of any other telecommands is considered an error condition.

Here is the call graph for this function:

void rt_pkt_diag (  unsigned char *  cmdPkt  )  [static]

Handles diagnostics communications test telecommands (func code = 0). Parameters: cmdPkt  A pointer to the telecommand packet buffer.

Here is the call graph for this function:

void rt_pkt_fill (  unsigned char *  pkt, unsigned short  patSelect, unsigned short  patLength, unsigned short  respLength )  [static]

Fills in the response data for a communication test telemetry packet. Parameters: pkt  A pointer to the telmetry packet buffer. patSelect  The pattern select code. patLength  The pattern length value. respLength  The response length value.

void rt_pkt_free (  void *  pkt, void *  arg )  [static]

Driver callback for telemetry packet completion. Parameters: pkt  The buffer for holding the packet. arg  User defined argument. Returns: A CTDB MSG code.

unsigned int rt_pkt_hkp (  void *  buf, void *  arg )  [static]

Driver callback for HKP telemetry packet generation. If a requested HKP communications test response is outstanding, one HKP telemetry packet is delivered. Parameters: buf  The buffer for holding the HKP packet. arg  User defined argument. Returns: A CTDB MSG code.

Here is the call graph for this function:

void rt_pkt_sc (  unsigned char *  cmdPkt  )  [static]

Handles diagnostics SC broadcase telecommands. Parameters: cmdPkt  A pointer to the telecommand packet buffer.

int rt_start (  void   )

Starts the remote terminal. Return values: 0  Success. -1  Failure.

Here is the call graph for this function:

int rt_stop (  void   )

Stops the remote terminal. Return values: 0  Success. -1  Failure.

Here is the call graph for this function:
