• Ctrl/S—Suspends output to the console terminal
• Ctrl/Q—Resumes output to the console
• Ctrl/C—Aborts the current command, if possible
The console program has no control over this once control has been passed to
another program such as an operating system or loadable diagnostic.
• Ctrl/R—Retypes the current command line
• Ctrl/O—Causes the console code to throw away output characters rather than
send them to the terminal
Entering another Ctrl/O resumes sending output characters.
• Up and Down Arrow—Used for command-line recall
13.1.2 Command Line Characteristics
The character sequence used for the prompt >>> is:
0Dh 0Ah 0Dh 3Eh 3Eh 3Eh 20h
This sequence is <CR>, <LF>, <CR>, >>> , <SP>. Host software executing a
binary load on the console terminal port can look for this character string to
determine when to respond.
Commands are limited to 80 characters. Characters entered after the 80th
character replace the last character in the buffer. Depending on your terminal,
these lost characters may be displayed but they are not included in the actual
command line.
The command interpreter is not case-sensitive. Lowercase ASCII characters a
through z are treated as uppercase characters.
Characters with codes greater than 7Fh are rejected by the parser. These
characters are acceptable in comments.
Type-ahead is not supported. Characters received before the console prompt are
checked for special characters (Ctrl/S, Ctrl/Q, Ctrl/C) but are otherwise discarded.
13.1.3 Radix Control
Numbers that you enter are, by default, interpreted as hexadecimal. You can
change the radix of input by entering %x before a number to specify hexadecimal
or %d for decimal.
