Serial Port I/O Function: Returns the baud rate, parity, data bits setting, stop bits, and other settings of the communications port.

[,ErrChar] [,EofChar] [,EvtChar])
port |
(Input) Integer. The port number. |
baud |
(Input; optional) Integer. The baud rate of the port. |
parity |
(Output; optional) Integer. The parity setting of the port (0-4 = no, odd, even, mark, space). |
dbits |
(Output; optional) Integer. The data bits for the port. |
sbits |
(Output; optional) Integer. The stop bits for the port (0, 1, 2 = 1, 1.5, 2). |
Binmode |
(Output; optional) Integer. 1 if binary mode is enabled; otherwise, 0. Currently, the value of this parameter is always 1. |
DTRcntrl |
(Output; optional) Integer. 1 if DTR (data-terminal-ready) flow control is used; otherwise, 0. |
RTScntrl |
(Output; optional) Integer. 1 if RTS (request-to-send) flow control is used; otherwise, 0. |
OutCTSFlow |
(Output; optional) Integer. 1 if the CTS (clear-to-send) signal is monitored for output flow control; otherwise, 0. |
OutDSRFlow |
(Output; optional) Integer. 1 if the DSR (data-set-ready) signal is monitored for output flow control; otherwise, 0. |
DSRSense |
(Output; optional) Integer. 1 if the communications driver is sensitive to the state of the DSR signal; otherwise, 0. |
OutXonOff |
(Output; optional) Integer. 1 if XON/XOFF flow control is used during transmission; otherwise, 0. |
InXonOff |
(Output; optional) Integer. 1 if XON/XOFF flow control is used during reception; otherwise, 0. |
XonLim |
(Output; optional) Integer. The minimum number of bytes accepted in the input buffer before the XON character is set. |
XoffLim |
(Output; optional) Integer. The maximum number of bytes accepted in the input buffer before the XOFF character is set. |
TXContOnXoff |
(Output; optional) Integer. 1 if transmission stops when the input buffer is full and the driver has transmitted the XoffChar character; otherwise, 0. |
ErrAbort |
(Output; optional) Integer. 1 if read and write operations are terminated when an error occurs; otherwise, 0. |
ErrCharEnbl |
(Output; optional) Integer. 1 if bytes received with parity errors are replaced with the ErrChar character; otherwise, 0. |
NullStrip |
(Output; optional) Integer. 1 if null bytes are discarded; otherwise, 0. |
XonChar |
(Output; optional) Character. The value of the XON character that is used for both transmission and reception. |
XoffChar |
(Output; optional) Character. The value of the XOFF character that is used for both transmission and reception. |
ErrChar |
(Output; optional) Character. The value of the character that is used to replace bytes received with parity errors. |
EofChar |
(Output; optional) Character. The value of the character that is used to signal the end of data. |
EvtChar |
Output; optional) Character. The value of the character that is used to signal an event. |
The result type is INTEGER(4). The result is zero if successful; otherwise, a Windows* error value.
