Stored procedures
Runs different functions that directly affect the bits of serial port, parallel port or infrared port, independently of the communication protocol. These functions are used to manage:
  • the DTR signal,
  • the RTS signal,
  • the XOFF and XON characters.
Remarks:
  • The port must be opened beforehand (sOpen).
Example
// Clears the DTR signal
sEscape(PortNum, "CLRDTR")
Syntax
<Result> = sEscape(<Port number> , <Function>)
<Result>: Boolean
  • True if the function was run,
  • False otherwise. If the port was not opened beforehand (by sOpen), sEscape has no effect.
<Port number>: Integer
  • Number of the relevant serial port: 1, 2, 3, ... 32 for COM1, COM2, COM3, ... COM32.
  • Number of the relevant parallel port: -1, -2, -3 or -4 for LPT1, LPT2, LPT3 or LPT4.
  • Number of the relevant infrared port: 1, 2, 3, ... 32 for IR1, IR2, IR3, ... IR32.
  • Port identifier returned by sOpen (if this function was called with a port name).
<Function>: Character string (with quotes)
Function to run:
CLRBREAKClears the "Break line" signal.
CLRDTRClears the DTR signal.
CLRRTSClears the RTS signal.
RESETDEVRe-initializes the device if possible.
SETBREAKEnables the "Break Line" signal.
SETDTRSends the DTR signal.
SETRTSSends the RTS signal.
SETXOFFThe transmission behaves like if the XOFF character was received.
SETXONThe transmission behaves like if the XON character was received.
