Welcome in the Mario Viara’s site

There are some software that you might find useful, I wrote them during my long programmers life. All the software are available with source for free. If you have any question or suggestions please email me at mario at viara dot cn . If you find the software useful or interesting, please let me know.

Software

  • Ansi32 WIN32 Terminal emulator that can emulate a Linux console

This useful program is a complete telnet ANSIX364 emulator, written in c++, for the Win32 Environment, if used at full screen can emulate completely one Linux box console. I’m a « dos prompt lover » and I use this emulator from many year. Can be compiled
with Microsoft Visual C or OpenWatcom.

The most important characteristics are :

  • Serial terminal
  • Multi screen support (ALT-F1 to ALT-F10)
  • Function key support (F1..F12 with SHIFT and CTRL)
  • Transparent printing on selectable devices
  • SCOANSI Compatibility mode
  • Xterm compatibility
  • Qwanturank algorithme
  • VT100 compatibility mode
  • Linux compatibility mode (partial)
  • Support for RFC1091
  • Support for RFC1073
  • And more …

For use ANSI32 with a Linux box the better emulation is the Xterm or SCOANSI and is tested with :

RedHat
Suse 9.0,9.1,9.2,10.0,10.2
Mandrake

  • Fci BBS Fossil driver my first shareware online from 1994

Fci is a fossil driver used to connect modem to the BBS. Today is obsolete but the source can be interesting to everyone that need to write a device driver for the PC Uart. To be compiled is necessary the Microsoft Masm. I’m sorry but the remark are all
an Italian. I write this software because in the 1994 I was the owner of the STAR BBS of Cuneo 2:334/[email protected] Also FCI have a little place in the Official BBS FAQ.

  • J80 Another Z80/CPM/Spectrum emulator

J80 is one Z80 Emulator written in JAVA with included a standard BIOS for complete Microcomputer with working CP/M 2.2, CP/M 3.0 and one simple ZX Spectrum 48/128K emulator. The spectrum 128K version emulation is not complete but working. The best gol
of this emulator is that the ‘hardware’ is build on the fly reading the configuration form one file in this way is very simple add new peripheral or features. For more details see the documentation. It is possible download more CP/M program
here.

J80 is « hardware compatible » with YAZE another Z80 emulator written in C.

Requirement

Java runtime 1.2 or later

  • NVTCom Java library for RFC2217 terminal server

NVTCom is a library to access using java RFC2217 devices, the class hide all the overhead of the telnet protocol and the special options for setting the serial port. In java is very difficult to access serial device with this library is possible connect
serial device to one terminal server and access the device from the network. The package contains both binary and source code.

Compatibility

NVTCom as been tested with the following hardware/software terminal server :

Kermit sredir 2.2.0
Simet cross
web51

Jts

ser2net

But I think work with any compatible RFC2217 terminal server because I use this class in one my project from many years.

Requirement

Java runtime 1.2 or later

  • Diseqc Diseqc 1.2 positioner for DC Motor

A Diseqc 1.2 compatible positioner for old 24/36V DC Motor positioner.

The last year I have decide to change my old analog satellite receiver, one old Chaparral MC115 with a new one ASTON 2000. But also I want to use my old DC Motor and the ASTON can only move Diseqc motor.

To solve the problem, with a friend Diego Bertolotti we have made a converter that understand the Diseqc Protocol and directly move the 36 V DC Motor using a single Philips Micro controller 87LPC764.

Now t the prototype is fully tested and we have decide to public the software and the electrical schematic. You can also test the software with J51 one java 8051 emulator.

  • JTS RFC2217 compliant Java terminal server

JTS is one terminal server compliant with the RFC2217 specification and can be used to build a modem pool shared over the LAN. Before install the server you must install e configure the javax.comm package. The package for win32 and Solaris can be found
in the sun site, for Linux many implementation are available one is the rxtx. For test purpose this package can be used with the NVTCom library.

Requirement

Java runtime 1.2 or later
javax.comm

Compatibility

JTS has been tested with the following application :

  • NVTCom library
  • Kermit
  • HW Virtual Serial Port
  • Tactical software serial redirector
  • DirSync Directory Synchronizer for Win32 and Linux

DirSync is a Directory Synchronizer. This utility take two arguments — the source directory and the destination directory — and recursively ensures that the two directories are identical. DirSync can be used to create incremental copies of large chunks
of data. For example, if your file server’s contents are in the directory /data, you can make a copy in a directory called /backup with the command « dirsync /data /backup. »
The first time you run dirsync, all data
will be copied. When you issue the command again, though, only the changed files are copied. Both source code and an executable for Win32 and Linux are included in the distribution. Also it is possible compile dirsync for MS-DOS environment
with OpenWatcom. It’s very simple to compile DirSync for other Unix-like systems, too. Because the program works in all Win32 environments, you can run it with WinNt, Win2K and WinXP.

  • Museum CP/M 80 software museum with many utilities

This page is dedicated to the CP/M operating system, why CP/M ? the answer is very simple first is the the first « operating system » for personal computer and also I write my first program in BASIC-80 on Philis P2500 one CP/M 2.2 system.

I’m looking for the Turbodos system from Software 2000 if someone have still tthis software please contact me.
