The serial send and receive histories logs the bytes being output or input through the ports. First, select
which port to log (1 or 2), and then specify the display. The bytes passing through the port may be
displayed as printable ASCII characters, hex values, or decimal values.
If you select ASCII characters, you must also choose how you wish to view non-printable characters. The
non-printable characters are denoted by boldface type and “<“ and “>“ parentheses. For example, an
ASCII “space” character, which is non-printable, may be displayed as decimal value
<32>
or hex value
<20>
.

The second diagnostic allows you to send a byte stream through the port specified at the top of the page.

To send a URL-encoded string, follow these three rules for encoding:
1. Enter your byte values as a string of printable ASCII characters and hex values. Spaces and
returns, for example, are non-printable characters and MUST be converted to hex.
2. Any hex value in the send string must be preceded by a “%” symbol.
3. The URL-encoded string does NOT accept decimal values, so if you only know the decimal
value of a byte, you MUST either convert it to a printable ASCII characters or the hex
