Property Value

When VTTek is set to true, a carriage return echoed from the host clears the bypass condition and is processed (the cursor moves to the left margin), and an immediately subsequent line feed is also processed. Likewise, a line feed echoed from the host clears the bypass condition and is processed (the cursor moves down a line), and an immediately subsequent carriage return will also be processed. When VTTek is set to false, a carriage return echoed from the host will clear the bypass condition, but will not be processed (the cursor doesn't move to the left margin); an immediately subsequent line feed also is not processed. Likewise, a line feed echoed from the host clears the bypass condition (the cursor doesn't move down a line), and an immediately subsequent carriage return will not be processed.

When VTTek is set to true and Reflection receives an EscLf sequence, Reflection won't process any line feeds until it receives a BEL or other no-op control code. Likewise, when VTTek is set to true and Reflection receives an EscCr sequence, Reflection won't process any carriage returns until it receives a BEL or other no-op control code. When VTTek is set to false and Reflection receives an EscLf sequence, Reflection treats the Lf as a sequence terminator until a subsequent BEL character is received. Likewise, when VTTek is set to false and Reflection receives an EscCr sequence, Reflection treats the Cr as a sequence terminator until a subsequent BEL character is received.

When VTTek is set to true, Reflection treats the character following the EscFs sequence as the first character of the point address. When VTTek is set to false, Reflection treats the character following the EscFs sequence as a gray scaling intensity character. Because Reflection does not support gray scaling, the character is ignored.

When VTTek is set to true, Tektronix GIN mode position reports are preceded by the DECLBD down sequence. If the DECLBD sequence is null, the position report and DECLBD sequence are not sent. When VTTek is set to false, Tektronix GIN mode position reports are not preceded by the DECLBD down sequence.

When VTTek is set to false, alphanumeric characters may be cut off or disappear off the top of the graphics area while emulating a Tektronix terminal. If this happens, setting VTTek to true moves these characters down to the top of the graphics area.
