Table 9-1. Configuration Commands (Cont'd.)

Command

lleanlng

 

 

Delete/insert:

 

AFIL=hhhh

Insert line code. Used in line 0 for reverse scrolling.

AFDL=hhhh

Delete line code. Used to speed up display on the Hazel-

 

tine 1510 and similar terminals.

 

 

Reverse video:

 

 

AFRV=hhhh

Start reverse video character(s). Used on the PROMPT

 

line display.

AFNV=hhhh

Return to normal video characters. Used to restore the

 

display after a reverse video line.

AI=Tor F

True if the CRT has invisible attributes. or False if the

 

attribute occupies a position on the screen.

AC=Tor F

True if the CRT has attributes per character, or False if

 

the attributes are per field.

 

 

Initialization/termination:

 

AFST=hhhh...

Start-sequence. This sequence is output to the terminal

 

when AEDIT-86 encounters it. Can be used to initialize

 

the terminal, e.g., to initialize a scrolling region.

AFEN=hhhh...

End-sequence. Output to the terminal when AEDIT-86

 

exists. Can be used to unset values that have been set

 

by AFST.

 

 

NOTES:

n(n1:n2) an integer in the inclusive range, n1 to n2.

ha 1-byte hex number.

hhhha 1- to 4-byte hexadecimal number.

hhhh...the same as hhhh, but the length may be up to 40 bytes.

TTor t indicates true.

FFor f indicates false.

stringa 0- to SO-character string.

9.1. 1 Configuration Command Notes

AT

This feature must be off (AT= F) for iRMX-based systems due to current

 

iRMX internal requirements. Setting AT= F directs AEDIT-86 not to

 

support type-ahead. Because the iRMX operating system performs type-

 

ahead, setting this function off does not affect the user.

 

When AT is off (AT = F), the AFCC function is not fully functional. The

 

synonym works only for synchronous operations (e.g., to terminate

 

INSERT mode), but not for asynchronous operations (e.g., exit from a

 

loop within a macro).

AB

The natural choice is ESC (I BH). However, this value cannot be used if

 

other terminal input functions begin with ESC (e.g., VTIO).

AFCC

AFCC is not fully functional if AT is off (AT= F). See notes on AT above.

9.2 Configuration Values

The hardware identification command AH may have several different values, e.g., a null string, the string S3E, the string S4. An AH command value implies a complete set of values for the entire configuration command set. Table 9-2 contains the default configuration commands with values for various terminals or systems.

AEDIT-86 specifications

The Intel AEDIT-86, also known as the Intel 8086, is a notable microprocessor that played a critical role in shaping the computing landscape. Released in 1978, it was Intel's first 16-bit microprocessor, setting the stage for the x86 architecture that continues to influence modern computing.

One of the main features of the AEDIT-86 is its 16-bit architecture, which allows it to process data in larger chunks compared to its 8-bit predecessors. This capability not only improves performance but also increases the amount of memory that can be addressed, allowing for a maximum of 1 MB of RAM. This was a significant advancement at the time, enabling more complex software and operating systems to run efficiently.

The AEDIT-86 is built on a 3-micron process technology, which was innovative for its time and contributed to its performance capabilities. The microprocessor operates at a clock speed of up to 5 MHz, which allowed it to execute more instructions per second than previous generations of processors. This speed, combined with its wide data bus (16 bits), enables the processor to handle a larger volume of information more quickly.

Intel incorporated several key technologies in the AEDIT-86, including segmentation. This feature divides the memory into different segments, making it easier for programs to access data and improving memory management. The AEDIT-86 also supports a minimum of four 64 KB segments, which enhances the organization and access of programs and data in memory.

Another significant aspect of the AEDIT-86 is its compatibility with the existing 8080 and 8085 instruction sets, which facilitated easier migration for developers and helped the processor gain traction in the market. This backward compatibility allowed existing software to be ported to the new platform with minimal modification.

Furthermore, the Intel AEDIT-86 introduced a powerful instruction set that includes both integer and string manipulation commands, paving the way for more versatile programming. The instruction set architecture (ISA) of the AEDIT-86 supports both high-level programming languages and low-level assembly language, offering flexibility for various applications.

In summary, the Intel AEDIT-86 is a groundbreaking microprocessor known for its 16-bit architecture, advanced segmentation technology, and compatibility with earlier instruction sets. Its introduction marked the beginning of the x86 architecture, which has influenced countless processors and computing systems that followed. The AEDIT-86's features and technologies were instrumental in the evolution of personal computing, laying the groundwork for future innovations in the industry.
