Vertical Channel Select (VCS)
Vertical Tab (VT)
The Vertical Channel Select (yCS) is a control code that causes a line feed function.
The Vertical Tab (YT) is a format control that moves the print position down to the
next vertical tab stop setting. Vertical tab stops are set by using the Set Vertical
Format function. If there are no vertical tab stops below the current print position,
the VT function causes a LF function.
To execute this command, the 3708 sends the number of ASCII line feed characters
(' OA ') needed to move the print element to the correct line.
Graphic Escape (GE)
Set Attribute (SA)
The Graphic Escape (GE) precedes another character and indicates that the
character that follows is to be printed from an alternate character set. The 3708
does not provide this function. The GE is printed as X' 60' .
The Set Attribute (SA) is an attribute defining code used to associate colors and
highlighting with strings of characters. These functions are not normally available
on ASCII printers. The 3708 prints this code as X '40' with no other changes in
format.
Configuration Options (Protocol Conversion)
Device Class
The following configuration option definitions apply to protocol conversion mode.
For configuration instructions, refer to IBM 3708 Network Conversion Unit Planning
and Installation.
Choices are Keyboard display, Keyboard printer, Printer, and Keyboard display
with printer.
Valid choices for protocol conversion operations are: Keyboard display, Printer,
and Keyboard display-with-printer.
Keyboard displays are video displays such as the IBM 3161. Printers are output
only devices such as the IBM 4201 Proprinter. Keyboard displays with printers are
video displays that allow their auxiliary ports to be remotely accessed, such as the
IBM 3163. These devices are supported as multiple LU (MLU) devices by the 3708.
Both the printer and the display can be accessed directly by the 3708.
Keyboard printers, which have a hard copy printer instead of a video display, can
also be supported in protocol conversion mode but must be defined as printers. The
3708 accepts the following input from these devices:
• Hold Print (' H' )/Enable Print (' E ')
• Cancel Print (' C') - LV type 1 SCS only
• PA1/PA2 - LV type 1 SCS only.
