Glossary

Terms

character attributes
Attributes that determine how characters look on the screen. For example, blinking and underline are character attributes.

configuration
A named collection of terminal emulation settings. These settings are contained in an .xml file or as embedded XML within an application.

end-of-text (ETX)
A character used to indicate the end of the text.

ENQ
An abbreviation that appears on a T27 session's status line and indicates that the session is in enquire mode. A session automatically enters this mode when the host is trying to send data and is unable to (for example, when the session is in local mode). You must put the session in receive mode to receive the data.

field attributes
Attributes that define the existence, appearance, or behavior of a field. For example, whether a field is protected or not is determined by the field attribute.

host
A mainframe, mini-computer, or information hub with which a PC or application communicates.

line transmission activity indicator (LTAI)
An abbreviation that appears on a T27 session's status line that indicates the session is connected to the host. If LTAI does not appear on the status line, a communication problem exists between the PC and the host.

operator information area (OIA)
A line of data that appears at the bottom of a session screen (status line). The status line displays such information as which mode the session is in and the cursor location. The OIA is not considered part of the presentation space.

presentation space
A specific number of columns and rows that define the area within which the host or user can display or type data.

P1024C
SITA implementation of the UTS, the UNISYS terminal protocol. It uses 7-bit (ASCII) characters and RID/SID for physical addressing.

terminal keystroke
A keystroke that a terminal (or application) sends to a host, for example, Transmit. You can send terminal keystrokes to a UTS, T27, 3270, 5250, or VT host session using the sendKeys method.
