		BOOLEAN	Talk
	)

Write some bytes to the IEC bus.

Parameters

Pdx	Pointer to the device extension.
Buffer	Pointer to a buffer where the read bytes are written to.
Count	Maximum number of characters to read from the bus.
Sent	Pointer to the variable which will hold the number of written bytes.
Atn	If true: Sent the bytes with set ATN; else, with released ATN
Talk	If true: A talk command is to be sent (some special care has to be taken at the end of the transmission).
