Read()

ScpiIOResult OpenTap.ScpiIO.Read ( ArraySegment< byte >  buffer, int  count, ref bool  eoi, ref int  read  )

inline

Reads a number of bytes from the instrument.

Parameters

buffer	The target buffer to read to.
count	The number of bytes to read.
eoi	This will indicate whether an EOI indicator was received.
read	The number of bytes that was actually read if succesful.

Implements OpenTap.IScpiIO.

ReadSTB()

ScpiIOResult OpenTap.ScpiIO.ReadSTB ( ref byte  stb )

inline

Reads the status byte of the instrument.

Parameters

stb	The current status byte.

Implements OpenTap.IScpiIO.

Write()
