    TuComHex Software V2.11 (Trial Edition) Release Note
======================================================================
Date: 04/19/2003

Operating Systems:
TuComHex software can be run on MS-Windows 95/98, MS-Windows NT 4.0,
MS-Windows 2000 and MS-Windows XP.

The following is a partial list of functions of the TuComHex software:
1. Editing the file in its binary (hex) format.
2. Comparing two files and marking those different bytes.
3. Sending binary data to other devices through the com port and
   RS-232 cable.
4. Receiving data bytes from the com port and displaying the hex
   value of the received data bytes in the Receive Pane of the
   Com Panel window.
5. Creating a new binary file by importing the hex values text in
   another file.
6. Exporting the hex display text in the TuComHex window to a text
   file.
7. Moving bytes among different files by using Copy Bytes and
   Paste Bytes commands.
8. Merging several files into one file by using Insert Bytes, Copy
   Bytes and Paste Bytes commands.
9. Using the Find dialog box to find the specified bytes.
10. Applying the bitwise shift,  bitwise mask,  one's complement
    and two's complement operation to the selected bytes.
11. Using different mark commands to mark specific bytes, blocks,
    patterns, and units in the TuComHex window.
12. The marking process can be stopped at any time.

Important Note:
If you have problems in sending data to the COM port or receiving
data from the COM port, please check to see if the port settings
(i.e., baud rate, byte size, parity and stop bits) matches
those settings on the device connecting to the PC. There are
many possibilities for causing the corruption of the data
transferred through the COM port, so if you are designing your
software on handling sending and receiving data through the COM
port, various safety mechanisms need to be built to ensure the
transferred data is valid.  TuComHex can be a very useful tool for
you to send data to or receive data from a device connected to the
COM port of the PC,  but you need to do many tests and adjust the
related port settings in TuComHex to make sure the data transfer is
correct. Since there are so many factors could corrupt the
transferred data, do not trust the data displayed on the screen
blindly.
To view or change the port settings for a specific open window,
use the Current Settings command.
If you want to make changes to the port settings and want to save
those changes so that every time when you open a new window,
the port settings of the new window will be initialized to those
values automatically,  you can use the Set Default command.
