7.4 Prefix and Suffix Handling
Prefixes and Suffixes are defined in text files (.prefix and .suffix) that reside on the reader. Readers
with default prefixes and suffixes are defined in the files .prefix.default
C([‘prefix’|’suffix’])<URL encoded text> will set the prefix or suffix to text. The prefix and suffix each
have a maximum length of 64 bytes. The URL encoded text must be in UTF-8 format. For standard
ASCII characters, this encoding is the same as ASCII. For extended ASCII (values of 0x80 through 0xFF)
the characters must be encode as a 2-byte sequence starting with either 0xC2 or 0xC3 (see
http://www.fileformat.info/info/charset/UTF-8/list.htm or http://en.wikipedia.org/wiki/UTF-8).
Exception: if JavaScript is being bypassed during decoding, then the prefix/suffix may be in extended
ASCII.
Example: C(suffix)%01X%1ean//n%04 will create a CodeXML
®
sequence to send the scancode for the
enter key.
Example: C(prefix)ol%c3%a9 will create a prefix of “olé”
8 File Installation
8.1 Simple Protocol
The file is split into blocks of 236 or less bytes each and downloaded to the Reader via 1, 2, & 5
commands using the following sequence:
1) Send a 1 command to initialize the download.
2) Wait for a d or e response from the Reader or a timeout.
a) If timeout or e response, restart the sequence at step 1.
b) If d response, continue to step 3.
3) Send a series of 2 commands, each with a portion of the file. (The Reader will not send
any response.)
4) Send a 5 command to end the download and install the file.
5) Wait for a d, e, or f response from the Reader or a timeout.
a) If f response or timeout, restart the sequence at step 1.
b) If e response, repeat step 5.
c) If d response, file download has completed successfully.
