Utility
The utility, TTY, in the “MOXA Standard COMM Driver” program group is
intended 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.
Existing Applications
Many Windows software packages, such as pcANYWHERE, LabView, FIX,
WinFax Pro, Fax Server, PROCOMM PLUS, LapLink, etc. can access the
Smartio
C104 COM ports directly since these applications follow the Microsoft Windows
COMM API.
