Hi,
I have many text files which contain some non-ASCII characters. I attach the screenshots of one of the files for people to have a look at. The issue is even after issuing the non-ASCII removal commands one of the characters does not go away. The character that goes away is the black one with a... (2 Replies)
Hi,
Is there a way to identify the lines in a file having extended ascii characters and display the same?

Hi,
I'm writing a BBS telnet program. I'm having issues with it not displaying lower ASCII characters. For example, instead of displaying the "smiley face" character (Ctrl-B), it displays ^B. Is this because i'm using Ncurses? If so, is there any way around this?
Thanks. (3 Replies)

srec_ascii_hex - Ascii-Hex file format
DESCRIPTION
This format is also known as the Ascii-Space-Hex or Ascii-Hex-Space format. If you know who invented this format, please let me know. If
you have a better or more complete description, I'd like to know that, too.
The file starts with a start-of-text (STX or Control-B) character (0x02). Everything before the STX is ignored.
Each data byte is represented as 2 hexadecimal characters, followed by an "execution character". The default execution character is a
space, although many programs which write this format omit the space character immediately preceding end-of-line.
The address for data bytes is set by using a sequence of $Annnn, characters, where nnnn is the 4-character ascii representation of the
address. The comma is required. There is no need for an address record unless there are gaps. Implicitly, the file starts a address 0 if
no address is set before the first data byte.
The file ends with an end-of-text (ETX or Control-C) character (0x03). Everything following the ETX is ignored.
It is also possible to specify a running 16-bit checksum using a sequence of $Snnnn, characters, although this usually appears after the
ETX character and is thus often ignored.
Variant Forms
In addition to a space character, the execution character can also be percent (%) called "ascii-hex-percent" format, apostrophe (') or
comma (,) called "ascii-hex-comma" format. The file must use the same execution character throughout.
If the execution character is a comma, the address and checksum commands are terminated by a dot (.) rather than a comma (,).
Size Multiplier
In general, binary data will expand in sized by approximately 3.0 times when represented with this format.
EXAMPLE
Here is an example ascii-hex file. It contains the data "Hello, World[rq] to be loaded at address 0x1000.
^B $A1000,
48 65 6C 6C 6F 2C 20 57 6F 72 6C 64 0A ^C
