DSS v1.61.9 (Oct 2006)
===========================
Author of patch: Vasil Ivanov

Estex DOS v1.61 for Sprinter Computer

Install: Put new files "system.dos" and "system.exe" to the disk.

1. Fixed bug that cause hang up of system or unexpected behaviour
when maximum limit if open descriptors was exceeded. Once, this bug
deleted whole disk "C" on my computer.

2. New function:

 Function #08 (DSS_RESCAN). Rescan system devices.
 input: no
 output: A - number of last disk in system

Function is used for RAM-disk creators. After disk created you
do not need to reboot the computer.

3. Before creating of new file functions 0Ah/0Bh
(Create file/New create file) check table of free descriptors.

4. Modified function 32h (wait of key press with echo)
that displays normal cursor.

5. Added history to standard shell. Size of history - 256 bytes.

Control of history:

   Esc        - clear command line
   Ins        - change input mode (insert/replace)
   Up/Down    - rotate of history
   PageUp     - to beginning of history
   PageDown   - to end of history
   Ctrl+Del   - remove history

Features:

 - Additional BAT-command "ECHO." to display empty line.

 - Modified command "DIR" that prints now disk labels and
   serial numbers.

 - Command CLS (clean screen) can take parameter of color,
   for example: CLS 2 (black background / green characters).

In the same time some known bugs of standard shell were fixed:

A. Fixed bug in command "ECHO" in BAT-files, where string longer
   than width of screen was cut by this width and tail of string
   was not printed.

B. Fixed bug in command "DIR" where string of path was limited to
   15 characters.

C. Fixed bug of changing current disk/path in case of error
   (for example after wrong filename).

P.S. This shell now needs new function #32 (wait of key press with echo)
that displays normal cursor.
