Due to the limitations of Windows 3.x operating system itself, only up to 9 COM
ports are supported, i.e., COM1 to COM9. Hence, C104 with 4 ports or other 4 port
non-intelligent boards, maximum 6 ports is supported if the existing standard COM
ports (COM1 and COM2) are included.
After successful installation, the MOXA program group will be created which
contains all the useful programs Moxa provided. Restarting Windows 3.x system
is required for MOXA Standard Windows-compatible COMM Driver after
installation. When system restarted, the MOXA COMM Driver is ready to go.
Driver Removal
The program, Remove , in the MOXA program group is provided to remove the
installed driver from the Windows.
Baud Rate Settings
For those
Smartio
C104 boards configured as High Speed Spectrum , the real
working speed is equal to 8 times of the displayed speed. For example, a port, if set
to Normal Speed Spectrum with 38.4 Kbps, will work at 38.4 Kbps for sure; while a
port, if set to High Speed Spectrum with shown speed 38.4 Kbps, will actually work
at 307.2 Kbps (38.4 Kbps

CONFIG and TTY, existing applications and programming which are described
later in this chapter.
Utility
The utility, TTY , in the MOXA 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.
