FBM216B模拟量通讯模块,FOXBORO中文使用说明
当观察任何167Bug命令的输出时，XON和对于终端端口有效的XOFF字符可以是如果启用XON/XOFF协议，则输入以控制输出（默认）。这些字符分别初始化为^ S和^ Q通过167Bug，但您可以使用PF命令更改它们。在初始化（默认）模式，操作如下：输入命令后，调试器将执行该命令然后会再次出现提示。但是，如果输入命令导致执行用户目标代码，例如GO，然后control可能返回或不返回调试器，具体取决于用户程序可以。
FBM216B模拟量通讯模块例如，如果指定了断点，则控件返回在调试过程中遇到断点时发送给调试用户程序的执行。或者，用户程序可以通过TRAP#496函数返回调试器调试器命令语法通常，调试器命令由以下部分组成：❏ 命令标识符（即内存的MD或MD显示命令）。注意，大写或小写都是允许。
❏ 如果命令设置为使用更多端口，则为端口号多个端口。
❏ 在第一个参数之前至少有一个中间空格。
❏ 命令指定的任何必需参数。
❏ 选项字段，由分号（；）分隔指定条件的步骤命令的默认条件除外。
这些命令使用修改后的Backus-Naur形式显示语法。使用的元符号包括：粗体字符串粗体字符串是文字，例如命令或程序名，并按其外观键入。斜体字符串斜体字符串是一个“语法变量”，将替换为它所代表的一类项目之一。
分隔两个或多个项目的垂直条表示要进行选择；只有一个应选择由该符号分隔的项目。
[]方括号中包含一个可选项。这个项目可能出现零次或一次。{}大括号括住可能出现的可选符号
零次或多次
When observing output from any 167Bug command, the XON and
XOFF characters which are in effect for the terminal port may be
entered to control the output, if the XON/XOFF protocol is enabled
(default). These characters are initialized to ^S and ^Q respectively
by 167Bug, but you may change them with the PF command. In the
initialized (default) mode, operation is as follows:
When a command is entered, the debugger executes the command
and the prompt reappears. However, if the command entered
causes execution of user target code, for example GO, then control
may or may not return to the debugger, depending on what the
user program does.
For example, if a breakpoint has been specified, then control returns
to the debugger when the breakpoint is encountered during
execution of the user program. Alternately, the user program could
return to the debugger by means of the TRAP #496 function
Debugger Command Syntax
In general, a debugger command is made up of the following parts:
❏ The command identifier (i.e., MD or md for the Memory
Display command). Note that either upper- or lowercase is
allowed.
❏ A port number if the command is set up to work with more
than one port.
❏ At least one intervening space before the first argument.
❏ Any required arguments, as specified by the command.
❏ An option field, set off by a semicolon (;) to specify conditions
other than the default conditions of the command.
The commands are shown using a modified Backus-Naur form
syntax. The metasymbols used are:
boldface strings A boldface string is a literal such as a command or a
program name, and is to be typed just as it appears.
italic strings An italic string is a “syntactic variable” and is to be
replaced by one of a class of items it represents.
| A vertical bar separating two or more items
indicates that a choice is to be made; only one of the
items separated by this symbol should be selected.
[ ] Square brackets enclose an item that is optional. The
item may appear zero or one time.
{ } Braces enclose an optional symbol that may occur
zero or more times.
