sParameter (Function) In french: sFixeParamètre Defines or modifies the parameters for configuring the specified serial port, parallel port or infrared port. This setting is optional. The default values are as follows: - Transfer rate: 9600 Bauds
- Parity: None
- 8 data bits
- 1 stop bit
Warning The settings for two linked workstations must be identical. Remarks: - The port must be opened (sOpen) before the call to sParameter. sOpen automatically initializes the serial port.
NumPort = sOpen("COM1", 2000, 2000)
IF NumPort <> 0 THEN
IF sParameter(NumPort, 9600, 1, 8, 0) THEN
ELSE
Error("Erreur de configuration de COM1", ErrorInfo(errFullDetails))
END
sClose(NumPort)
ELSE
Error("Erreur d'ouverture de COM1", ErrorInfo(errFullDetails))
END
Syntax
<Result> = sParameter(<Port number> , <Rate> , <Parity> , <Nb Data Bits> , <Nb Stop Bits> [, <DTR/DSR> [, <RTS/CTS> [, <XON/XOFF>]]])
<Result>: Boolean - True if the parameters have been initialized properly,
- False otherwise. HErrorInfo returns more details.
Note: If the port has not been previously opened (by function sOpen), function sParameter has no effect..
<Port number>: Integer Identifier of the port used: - Port number:
- Serial port number: 1, 2, 3, ... 32 for COM1, COM2, COM3, ... COM32.
- Parallel port number: -1, -2, -3 or -4 for LPT1, LPT2, LPT3 or LPT4.
- Infrared port number: 1, 2, 3, ... 32 for IR1, IR2, IR3, ... IR32.
- Port identifier returned by sOpen (if this function was called with a port name).
<Rate>: Integer Rate for data transfer (expressed in Bauds or Bits per second). <Parity>: Integer Parity of the transfer:
| | | 0 | No parity | | 1 | Even parity | | 2 | Odd parity |
<Nb Data Bits>: Integer Number of bits per character: 4, 5, 6, 7 or 8. <Nb Stop Bits>: Integer Number of stop bits:
| | | 0 | 1 stop bit | | 1 | 1.5 stop bits | | 2 | 2 stop bits |
<DTR/DSR>: Optional integer - 0 (or False, default value) if the DTR/DSR protocol must be ignored and if it should be in "active" mode.
- 1 (or True) if the DTR/DSR protocol must be in "Handshake" mode,
- 2 if the DTR/DSR protocol must be ignored and if it should be in "inactive" mode.
For more details, see the documentation for managing communication ports.
<RTS/CTS>: Optional integer - 0 (or False, default value) if the RTS/CTS protocol must be ignored and if it should be in "active" mode.
- 1 (or True) if the RTS/CTS protocol must be in "Handshake" mode,
- 2 if the RTS/CTS protocol must be ignored and if it should be in "inactive" mode.
For more details, see the documentation for managing communication ports.
<XON/XOFF>: Optional boolean - True if the XON/XOFF protocol must be taken into account,
- False (default value) if this protocol must be ignored.
