Utilities

The utility, TTY, is included to help users monitor and debug RS-232

communications under Windows 3.x which can manipulate ports from COM1 to

COM9. It is just a simplest example program which can send and receive data after

each port opened with selected communication parameters. Multiple windows for

ports simultaneously are available for a demonstration of multitasking feature of

Windows 3.x. The Windows-provided application, Terminal, can only make use of

COM1 to COM4 which is obviously a restriction.

Windows 3.x COMM API Programming

MOXA Windows-compatible COMM Driver supports Microsoft Windows COMM

API such as OpenComm(), ReadComm(), WriteComm(), etc. It supports any language

conforming to the Windows COMM API like Microsoft C, Borland C, Visual C, Visual

Basic, Delphi, etc. Sample programs for only Microsoft C, Borland C and Visual Basic

are supported. For other languages' sample programs, please refer to the language-

provided communication example programs.

Application Note

Many Windows software packages, such as pcANYWHERE, LabView, FIX, WinFax

Pro, Fax Server, PROCOMM PLUS, etc., can access MOXA COM ports directly since

these applications follow the Microsoft Windows COMM API. On the contrary,

those Windows applications not fully compatible with Windows COMM API
