I have developed some softwares.

• BbShell - BBS host program (Modula-2/09)
  This is available for both amateur packet radio and phone lines. This BBS is OK for multi-user access at same time because this is running on multi-tasking OS, and using record lock function by system call to avoid duplicate access. Command line syntax is quite particular, but this is familiar with machine-to-machine communications such as autopilot access of BBS. Also this BBS program can receive and send NAPLPS data directly.

• MForm - Simple text formatter (Modula-2/09)
  When I was using OS-9, I had only line editors and small screen editors as text processing tools. This is a naive text formatter which lacks page layout and font modification functions, because it was intended to use only for on-line text files. MForm is based on a same tool shown in the book ``Programming Tools'' by B. W. Kernighan and P. J. Plauger. Of course this can handle Japanese (MS-Kanji code) texts.

• NetWalk - Terminal program (Modula-2/09)
  On FM-11, I have two terminal program - telcom and AXCom. But I don't like both, So I started to write new terminal program. This program supports following functions;
  • high baud rate speed (up to 9600bps)
  • macro command
  NetWalk communicaton kit contains following programs;
  • NetWalk - normal terminal program
  • Nwc - macro compiler
  • Nwx - communication daemon ran under NetWalk macro
  • nwsked - scheduler for Nwx invocation

• Nono.l - Puzzle solver (Lisp-09)
  This lisp program derives solutions for Nonogram puzzle (nowadays more well known as ``PICROSS'' by Nintendo). I wrote this program as my lisp programming exercise.

• TimeSp - Timecode Superimpose generator (TURBO Pascal 5.5)
  At road race such as marathon or Ekiden, there is a time display on the corner of TV screen. This generates such display images, then converted to a NTSC video signal by a scan converter to superimpose a live screen.

• VTRCHART - VTR operating time table plotter (FTL Modula-2, etc.)
  Before this, they wrote time table of daily VTR operation by the hand. Core part of VTRCHART is a filter which converts CSV format operation data to character sequence for a XY plotter. VTRCHART package contains MENU.EXE, ME.EXE (screen editor) as a user interface, VTRCHART.EXE as a filter, and some batch files. This is only just a kluge. :-)

• SatSv - TV satellite supervisor (FTL Modula-2)
  At our TV relay transmitting sites, OKITECS OT-310 and OT-300 telemeters / telecontrollers are used to monitor and control the status of transmitters over NTT dial-up circuits. SatSv makes such operation more easier and more efficient by attaching to OT-310 through RS-232C line. SatSv supports following functions;
  • Monitoring 60 sites at maximum.
  • Monitoring/Controlling following items for each site.
    • monitoring 12 make/break switch status
    • monitoring 2 analog voltages
    • controlling 4 make/break switches
  • transaction log to a scrollable window, a disk file and/or a printer
  • scheduled operation automatically
  • standalone debug log to trace itself
  • error detection and retry on communication (OT-310/300 has no error-recovery mechanism)
  In SatSv, main routine is emulating multi-tasking kernel. And three processes are running on that core part. These processes are communication, user interface and timer process. Multi-tasking is implemented by Co-routine mechanism of Modula-2 language.

• erp - TV magneto-electro field simulator (FTL Modula-2)
  At maintenance service of TV transmitting system, measuring magneto-electro field strength is an important job. Such strength is able to be derived from the power of transmitter, antenna gain, distance between TX and RX. The program called erp figures out the distribution of the strength map on a specified area.

• gplot - simple graph plotter (Perl)
  gplot is a perl script to draw graphs by XY-plotter. It makes more easier to layout its size, position, line-type, etc. If gnuplot runs on MS-DOS, I wouldn't write this. :-)

• bs.awk - article summary generator (awk)
  This is a awk script to generate summerized report for postal activities on SIN-NET (my favorite local BBS).

• bt - blind typing trainer (C)
  This tests and evaluates your typing ability. I wrote this program to learn C programming with termcap library.

• erp - UNIX/X11 version of erp (p2c, gcc, Xlib)
  This was transported from MS-DOS version of erp. Original pascal source was rewrited to remove DOS-oriented part, then converted to C source code by p2c translator, then finally drawing routines are replaced to equivalent ones of X11 and linked.

  • TNN Takada TV (gif image, modified by xv)
  • TNN Aikawa TV (gif image, modified by gnuplot)

• sortcc - sorting by comment chain of NIFTY Serve access log (Perl)
  If you have access log files of NIFTY Serve, you can re-sort them by comment chain order (same as ``thread'' on netnews) by using this little perl script.
  More powerful and useful tools are under development derived from this sortcc.pl.

• sin2html - SINNET access log to HTML converter (Perl)
  SIN-NET is a local BBS which I'm familiar with. This perl script reads its access log then writes the output converted to HTML format to viewing by any WWW browser. In output, an index list at head, and goto-tags at each article are added.

• kermits - Kermit macro package for NIFTY Serve (Kermit macro)
  This kermit macro connects to NIFTY Serve then exchanges e-mail and reads new messages on specified forums. Kermits is stored in the data library of UNIX forum (FUNIX) and was introduced in JF document.

• logview.el - Simple log browser (Emacs Lisp)
  This is an Emacs Lisp program for reading log file of some BBS's. Every article is narrow-displayed and numbered. You can jump to and refer a specified article quickly.

• tksamples - Tcl/Tk sample programs (Tcl/Tk)
  I'm exercising this programming language. Please wait :-)
