10 TERMINAL WINDOW

10.1 Introduction

Xplor8 has an integrated terminal window which allows the user to send and receive bytes with a

connected MCU, provided a suitable program is running on the MCU. Bytes may be sent as ASCII

text, or in their hexadecimal representation. A demonstration HC908 program is included in the

distribution file; this is in assembly language and will need compiling to suit the memory architecture

of the proposed target MCU - see the section on the Terminal Demonstration Program below.

The terminal window may be activated by:

• clicking the item in the View menu of the main form,

• typing the keyboard shortcut Ctrl+T, or

• issuing the command 'Term' (see Launch Terminal Window) on the command line.

10.2 Window Layout and Features

The window is divided into two panes. The left hand pane displays bytes sent (black) and received

(red) in their alphabetic representation as far as possible. Non-printing characters display as hollow

rectangles (this option may be suppressed - see Terminal Window Settings below). The right hand

pane displays the same characters in their hexadecimal representation, as pairs of numbers in the range

00 to FF.

The division between the two panes is a moveable splitter bar, by default the right hand pane is twice

as wide as the left hand one because the hex representation of bytes takes twice the width of their

ASCII form.

Bytes may be entered in either pane at will. The <Tab> key will swap between panes. The currently

active pane is highlighted in aqua. Only printable characters can be entered in the left hand pane.

The <Backspace> key operates differently in the two panes. On the left, it erases the on-screen

characters and, if 'Send Immediately' is in force, also sends the backspace character ($08) to the MCU.

On the right it either erases the first character of a part-complete byte, or both characters of a complete

one, but in no case does it transmit the $08 byte.

The action of the <Enter> key depends upon the terminal settings. The terminal can be configured

either to send bytes immediately they are typed, or only upon pressing <Enter>. In the latter case,

additional bytes can, optionally, be sent when <Enter> is pressed. These bytes may be chosen by the

user.

Word wrapping may be enabled in the two panes, from the 'View' menu.

The terminal window uses the communication baud rate selected in ‘Baud Rates’ on the

Settings>COM Port tab, and the COM port must be connected (opened) before the terminal can be

used.
