PT250 Settings

This dialog box is displayed by selecting PT 250 in the Settings menu.

Screen Format

Factory default: 80 x 24

The setting of this option determines the display memory format, the number of lines and columns that are displayed, and the amount of data transmitted to the host when the emulation is in Block mode (as determined by the setting of the Block Mode option in this dialog box).

Selecting 80 x 24 will enable 24 rows of 80 columns to be displayed at the same time. In Block mode, this specifies 1-page mode transmission.

Selecting 80 x 48 will enable 80 columns by 24 rows to be displayed, while another 24 rows are stored off-screen in the display buffer. These may be scrolled into view using the scroll bar. In Block mode, this specifies 2-page mode transmission.

Selecting 132 x 27 will enable 27 rows of 132 columns to be displayed at the same time, useful for spreadsheets. In Block mode, this specifies 1-page mode transmission.

Selecting 80 x 25 will enable 25 rows of 80 columns to be displayed at the same time. In Block mode, this specifies 1-page mode transmission.

Block Mode

Factory default: Unselected

The setting of this option determines how data is transmitted to the host.

When unselected, each character entered from the keyboard is immediately sent to the host which processes it then echoes it back to the display.

When Block mode is selected, characters are displayed but not sent to the host until the Enter key is pressed. The size of the block of characters is determined by the Line Block Mode option.
