The program is intended for transmitting of bytes to serial ports, manipulating by their baud rate, controlling of their LCR and MCR registers and of system speaker according to arbitrary timetable defined in user-written script file. All events are reflected on the screen. This program can be useful to people that develop devices connecting to computer by serial ports.

Capture (record) digital data via LPT port. View/edit data in binary format (two modes), save it to a file as reference or for "playback" via LPT port to simulate data source. Also, the editor allows you to create your own digital data for "playback". Other features includes an adjustable frequency square wave generator, an LPT port tester, an activity (LPT port pin) counter, etc.

RS232 v1.07 is an RS-232 bus analyzer program. Use it to capture RS-232 communications between 2 devices so you can analyze and debug protocol problems. The program will use all existing conventional RAM for the read buffer, up to 500,000+ bytes. The RS232 program has been highly optimized in assembly language for the best possible performance. The RS232 program has the ability to search for specific ASCII or Hex data and can also write the read buffer to disk for viewing at a later date. ...

ResQ232: Makes DOS an RS232 line monitor

console mode program CONSOLE, and documenation for their use. The PORTS program reports all serial port UART addresses and UART types for the 8250, 16450, 16550, 16650, and 16750. The TEST and CONSOLE programs are used to test the functionality of a specfic RS232/422/485 port. ports20.zip has replaced ports11.zip. Freeware. Uploaded by the author.

screen all the time. It shows the real-time bit rate, data/parity/stop bit information, and status of the control leads (DTR, DSR, RTS, CTS, RI, and CD). It can show any of the standard COM ports (COM1 - COM4) or a special serial port of your choosing. It can be controlled either with command line options or with a configurable Hot-Key. Hot-Key controls include moving around on the screen, hiding/showing itself, and changing the COM port, among others. Special requirements: None. Freeware. Up...

DESCRIPTION: 16550 is a shareware program designed to allow the 'unlocking' of the internal fifo buffer present in the UART chip of the same name. The program will scan all four COM ports (COM1: - COM4:) available on the PC and report the presence (if any...) of the 16550 UART. The user may optionally set the various parameters necessary to utilize this buffered mode of operation.
