The Auto Repeat feature can be disabled from the Z88 Panel by setting the repeat rate to 0, or from Setup B of Vision/L by setting auto repeat to No.
Auto Xon-Xoff On/Off
Auto Xon-Xoff can be enabled or disabled from the Z88 Panel. If enabled, transmission of data to and from the Z88 is controlled by the Xon-Xoff protocol. When either Vision/L or the host computer need to suspend data transmission, an Xoff is issued to the sending device. When the receiving device is free to continue it sends an Xon to the sending device.
Bits per character 8/7
Vision/L will always transmit and receive 8 data bits per character. On transmission, 1 start bit and two stop bits will be sent. On reception, 1 start bit and 1 stop bit will be expected.
With the option set to 7 bits, only the first 7 bits of the character are actioned. This will typically be the required setting for VT100 emulation. With the option set to 8 bits, all 8 bits of each character received are actioned. This provides the host with the facility to use 8 bit control characters and the DEC supplemental graphic set. Typically, this may be necessary for VT220 emulation.
Cursor Block/Underlined
The cursor used by Vision/L is the standard Z88 flashing block.
Margin Bell On/Off
No margin bell is sounded.
New line On/Off
When New Line is off, a received line feed, form feed or vertical tab will move the cursor to the next line in the current column. The -ENTER- key transmits a carriage return.
When New Line option is on, a received line feed, form feed or vertical tab will move the cursor to the first column of the next line. The -ENTER- key transmits both a carriage return and a line feed.
Parity Sense
The parity of transmitted characters can be set to Odd, Even Mark, Space or none from Setup mode B. The parity of received characters is always ignored.
Scroll Style
After the screen is full, each new line is added as a complete character line, giving the effect of "Jump scroll".
Screen Background
Light mode means the screen of the Z88 is in normal mode, i.e. black characters on a light background.
Keyclicks Audible/Silent
Keyclicks are enabled or disabled using the Z88 Panel option.
-SHIFT-3 is £/#
In Vision/L, both the keys -SHIFT-3 and £ cause the code for '#' to be transmitted to the host. The character displayed on the Z88 screen is determined by the setting of this option and can be either '#' or '£'.
Auto wraparound On/Off
When Auto wraparound is on, the 81st character inserted on a line is automatically placed in the first character position of the next line.
When Auto wraparound is off, the 81st character and all subsequent characters are placed in the 80th character position until a control character is received.
Interlace Off/On
This feature concerns the scan rate on a Cathode Ray Tube and is thus not supported by Vision/L.
