XON/XOFF

This feature controls the genera,tion of the XOFF (default, OC3) and XON (default, OCl) synchronization codes. These codes ensure that data from the host computer is not lost •. With Auto XON/XOFF enabled,

the XOFF code is transmitted under any of these conditions:

o The receive FIFO buffer is almost full.

o You press CTRL-S.

The XON code is automatically generated to resume host transmission under any

Raster Technologies Model One/IO Introduction and Installation Guide

o The receive FIFO buffer is almost empty and an XOFF code was sent.

o You press CTRL-Q.

The XON and XOFF codes are Model One/IO special characters and can be

. changed with the SPCHAR command.

13.6.10 Newline

'The Newline feature controls line feeds. with ~ew1ine disabled (default) pressing RETURN generates only the CR (Carriage Return) code. With this feature enabled, pressing RETURN generates both the CR and the LF (Line Feed) codes.

You can also disable/enable this feature with the host with escape sequences (see Sections 15.2.9.1 and 15.2.9.2).

13.6.11 Autowrap

. Autowrap determines whether or not, as you type, the cursor automatically advances to the first position of the next line immediately after you enter a character into the last position of the current line.

With Autowrap disabled (default), when you get to the end of a line as you are typing, the cursor remains in the last column and successive characters that you enter overlay the last character on the line. With Autowrap on, the cursor and the newly entered text automatically wrap around to the beginning 'of the next line.

You can also select this feature with the host (see Sections 15.2.9.11 and 15.2.9.12).

13.6.12 Cursor Type

There are two cursor types, a blinking underscore (default) and a blinking block •.

13.6.13 Reverse Screen

Enabled, this feature allows you to reverse the text color with the background color, whether these colors are the defaults, white and black, or whether you specified other colors either in Setup B (see Sections 13.6.19 and 13.6.21) or with a control sequence (see Section 15). Disabled is the default.

13.6.14 Control Codes Displayed

with this feature enabled, "hex" codes are displayed when you type control codes or escape sequences. For example, if you type:

ABC CTRL-A DEF you see displayed:

ABC<Ol>DEF 13.6.15 Display Format

If you do not want the default, 24 x 80, select another display format by specifying the number of rows across and the number of lines down. These formats are available:

Rows and Columns 15 x 40

15 x 80 24 x 40 24 x 80 24 x 128 30 x 40 30 x 80 30 x 128 60 x 80 60 x 128

Note that some character distortion occurs for screen formats with 128 columns and/or 60·tows due to the smaller size characters required.

13.6.16 Sqlid Background

With this feature disabled (default), there is a graphics background.

Otherwise, the background is solid. This option controls the display of bit planes 0-7 while you are in te~t mode.

·13.6.18 Background Color

The screen's default background is Color Number 0 but it can be any color you select fram the Model One/la's available colors. Use this feature to select a background shade. The default values, displayed wh~n you initially select the Background Color feature in Setup B (see Figure 13.4), are R=OOO, G=OOO, B=OOO--in effect, a black background.

To change these values, press

13.6.19 Blinking Text Color

Use this feature if you have enabled blinking text and you want to specify. a text color other than black.

Blinking text can be any color you select from the Model One/lO's available

colo~values. The default values, displayed when you initially select the Blinking Text Color feature in Setup B (see Figure 13.5), are R=OOO, G=OOO, B=OOO.

To change these values, press

14. Using Keyboard Controls and LED IndIcators

The Model One/10's keyboard has 1) dark gray ~ontrol keys, a set of, 12 programmable function keys, a' set of keypad keys, and'seven LED indicators.

Some of these keys are:

o

^SET-UP

IEOC I

IcrRL I

o

ITAB I

o IPF11

This section discusses the keyboard's control keys, function' keys, and LED indicators. .The; effects of some of these, 'keys vary according to the set-up ',' features (see Section' 13) you selected. Note that the following control key descriptions assume that you activated the Local Echo feature and that transmitted codes are "echoed" back to the 'terminal (the transmitted codes have no effect on the tenninal unless they are echoed).

The Model One/lOis keyboard is illustrated in Figure 14.1.

^{SET-UP I}

Use this key to enter and exi t Setup Mode (see Section 13). After you enter this mode, if Auto XON/XOFF is ,enabled, the tennina1 sends the XOFF code (DC3) when the input buffer becomes nearly full. The characters in the buffer are then displayed when you exit Setup mode.

While you are in Setup mode and AutoXON/XOFF is disabled" overrun errors can occur when the host continues to send data.

Pressing this key converts lower case alpha key codes· to uppercase before they are transmitted. Note that neither numeric, symbol, nor special keys are affected by CAPS LOCK.

The NOSCRL key (no scroll) alternately transmits XOFF and XON codes;

this is equivalent to your pressing CTRL-S and CTRL-Q.

This key has two functions. First, it can transmit the CR control code (octal 015) which moves the cursor to the first column of the current line. Wi th the New Line feature enabled (see Section 13.2.11), pressing RETURN transmits both CR and LF control codes, thus moving the cursor to the first columri of. the next line.

The second function is terminating both host and local Model One/10 command lines.
