Full ASCII Extension to Code 39
"Full-ASCII Code 39" expands the Code 39 character set to include all 128 ASCII characters. Symbols 0-9,
A-Z and punctuation characters and are identical to their Code 39 representations. Lower-case letters,
additional punctuation characters, and control characters are represented by sequences of two Code 39
characters.
This table depicts the Full ASCII character set as a function of Code 39 characters:

Accumulate Mode
Accumulate Mode is an option allowing the RF Terminal to accumulate multiple bar codes in its buffer, then
transmit them to the computer as if they had been a single bar code. This is useful for entering quantities and
other variable data.
Accumulate Mode works with Code 39, Code 93 and Code 128 only and can't be used with a check digit.
When the RF Terminal reads a bar code with a space as the first character, it beeps and buffers the data
without transmission. It continues to read and buffer bar codes (up to 40 characters) until it reads a bar code
without a leading space. Once it reads this last bar code, the entire buffer (including that last code) is
transmitted as one long bar code. A “double-minus” sign (--) bar code clears the buffer. The ENTER code
on this Barpad is a Code 39 Start/Stop Character only.
