SendDirect(<xCodes>, [<cPortName>]) --> lSuccess

Arguments

<xCodes> --> is an ASCII code, a character or character string, or a collection of numbers or letters.

* Send ASCII code 27 to LPT printer port 1

SendDirect(27, "LPT1")

* Send ASCII code 27, 15, 1 to printer port 1

SendDirect(CHR(27) + CHR(15) + CHR(1), "LPT1")

* Send ASCII code 27, 15, 1 to printer port 1

SendDirect( { 27, 15, 1 }, "LPT1")
