Commands:
| Name | Description |
|---|---|
| StateInput: DevVoid Output: State State Code |
This command gets the device state (stored in its <i>device_state</i> data member) and returns it to the caller. |
| StatusInput: DevVoid Output: ConstDevString Status description |
This command gets the device status (stored in its <i>device_status</i> data member) and returns it to the caller. |
| DevSerWriteStringInput: DevString String to write Output: DevLong Number of characters written |
Write a string of characters to a serial line and return the number of characters written. |
| DevSerWriteCharInput: DevVarCharArray Characters to write Output: DevLong Number of characters written |
Write N characters to a seria line and return the number of characters written. |
| DevSerReadStringInput: DevLong type of read SL_RAW SL_NCHAR SL_LINE Output: DevString String read |
Win32 method : Read a string of characters, the type of read is specified in the input parameter SL_RAW SL_NCHAR SL_LINE |
| DevSerReadCharInput: DevLong type of read SL_RAW SL_NCHAR SL_LINE Output: DevVarCharArray Array of characters read |
Win32 method : Read an array of characters, the type of read is specified in the input parameter, it can be SL_RAW SL_NCHAR SL_LINE |
| WriteReadInput: DevVarLongStringArray type of reading strategy(RAW,NCHAR..),command to write on the port com Output: DevString response of the device behind the serial line |
This method permit to send a request to a device throw the serial line and returns the response of the device. The commands write and read don't return until they have not finished. |
| DevSerGetNCharInput: DevVoid no argin Output: DevLong number of char available in receiving buffer |
Return the number of chars available in receiving buffer |
| DevSerReadNCharInput: DevLong number of the caracters to read on the serial line Output: DevString pointer to the string read updated |
Read a string of N characters from the serial line If there are no characters to be read returns an empty string. |
| DevSerReadRawInput: DevVoid no argin Output: DevString pointer to the string read updated |
read a string from the serialline device in mode raw (no end of string expected, just empty the entire serialline receiving buffer). |
| DevSerReadLineInput: DevVoid no argin Output: DevString pointer to the string read updated |
read a string from the serialline device in mode line (up to and including the character specified by the NewLine property |
| DevSerFlushInput: DevLong flush to do 0=input 1=output 2=both Output: DevVoid no argout |
Win32 method : Flush serial line port according to argin passed. |
| DevSerSetParameterInput: DevVarLongArray device parameters in pair Output: DevVoid no argout |
Set serial line parameters |
| DevSerSetTimeoutInput: DevShort Value of the timeout to set Output: DevVoid no argout |
This command sets the new timeout (in ms). |
| DevSerSetParityInput: DevShort The new parity to set. Output: DevVoid no argout |
Sets the new parity of the serial line. NONE 0 ODD 1 EVEN 3 |
| DevSerSetCharLengthInput: DevShort The new charlength to set Output: DevVoid no argout |
Sets the new charlength. 0 = 8 bits 1 = 7 bits 2 = 6 bits 3 = 5 bits |
| DevSerSetStopbitInput: DevShort The new stopbit to set Output: DevVoid no argout |
Sets the new stop bit. 0 = none 1 = one stop 2 = 1.5 stop bit |
| DevSerSetBaudrateInput: DevULong The new baudrate to set Output: DevVoid no argout |
Sets the new baudrateof the serial line ( up to 4 Mega). Default is 9600. |
| DevSerSetNewlineInput: DevShort The new line character to set Output: DevVoid no argout |
The new ending character in hexa. Default is 0x13 (=CR |
| DevSerReadRetryInput: DevLong number of reading retries Output: DevString pointer to the string read updated |
read a string from the serialline device in mode raw (no end of string expected, just empty the entire serialline receiving buffer). If read successfull, read again "nretry" times. |
| DevSerReadNBinDataInput: DevLong nb char to read Output: DevVarCharArray array of data |
Read the specified number of char from the serial line. If the number of caracters is greater than caracters avaiable, this command returns all caracters avaiables. If there are no characters to be read returns an empty array. |
| DevSerWaitCharInput: DevVoid Output: DevLong Number of charcters in reading buffer |
Command blocks until a char is available or the timeout expired. If the timeout value is 0 then the command returns immediately with the number of chars available if any or timeout error if no char available |
| DevSerSetParameterCompatInput: DevVarShortArray Device parameters in pairs as a short array Output: DevVoid no argout |
Set serial line parameters. The command is the same as DevSerSetParameters, but takes the parameters as a short array for compatibility with the old Taco interface. |
| DevSerFlushCompatInput: DevShort flush to do 0=input 1=output 2=both Output: DevVoid |
Flush the serial line port according to argin passed. The command is the same as DevSerFlush but takes the input parameter as short value for compatibility with the old Taco interface. |
Pipes:
Properties:
| Name | Description |
|---|---|
| SeriallineDevString | The path and name of the serial line device to be used. |
| TimeoutDevShort | The timout value im ms for for answers of requests send to the serial line. This value should be lower than the Tango client server timout value. |
| ParityDevString | The parity used with the serial line protocol. The possibilities are none, even or odd. |
| CharlengthDevShort | The character length used with the serial line protocol. The possibilities are 8, 7, 6 or 5 bits per character. |
| StopbitsDevShort | The number of stop bits used with the serial line protocol. The possibilities are 1 or 2 stop bits |
| BaudrateDevLong | The communication speed in baud used with the serial line protocol. |
| NewlineDevShort | End of message Character used in particular by the DevSerReadLine command Default = 13 |
| SimulatedDevBoolean | If this property is true, do not connect to the serial port. It is used when another device simulated this one. |
| SimulatedDevBoolean | If this property is true, do not connect to the serial port. It is used when another device simulated this one. |
