Intellio C320Turbo User's Manual 3-37
Windows 3.x
For users who need to implement an industrial control system or data acquisition
system in the Windows 3.x environment, Moxa has developed two device drivers
and/or library functions under Windows 3.x which is called Windows 3.x API-232.
You should find the Dos/Windows 3.x driver diskette along with shipment in addition
to API-232 User's Manual.
In this chapter, driver installation and configuration procedure are described. Utility,
TTY, is explained, which is good for terminal emulation. Related issues such as driver
removal, programming and existing applications are also stated.
Installing Driver
MOXA Windows 3.x API-232 is a software package that assists users to develop
and/or debug programs for serial communications. It includes two different types of
Windows 3.x drivers:
1. MOXA Windows-compatible COMM Driver: for the MOXA Smartio C104
Family, Intellio C218/C320 Series only.
2. MOXA Proprietary Windows DLL Driver: for Intellio C218/C320 Series only.
The installation program, WININST.EXE, which asks the user to choose the desired
driver for the selected MOXA board and also prevents the possibility of driver
installation confusion. The two types of drivers could not coexist in a system, in
other word, only one type of driver could be enabled in one system and removal of
previous different type of driver is required.
Carefully examine which one of the two drivers is suitable for you. Here is our
suggestion: If you need no more than 9 serial ports or intend to run an already made
software program (such as pcANYWHERE for Windows) that supports Windows
Win16 SDK COMM API calls, then choose MOXA Windows-compatible COMM
Driver as your platform. If you need more than 9 serial ports or have been familiar
with the MOXA API-232 functions, then MOXA Proprietary DLL Driver would be
suitable for you. In this case, developing the Windows application by yourself is
necessary.
