UPort 2000 Series
Driver Installation
2-12
The Ports Configuration page settings are described below.
Port Settings
Auto Enumerating COM Number
If the Auto Enumerating COM Number checkbox is checked, COM numbers will be assigned automatically
and in sequence to the ports. E.g., COM3 to Port 1, COM4 to Port 2, etc.
If you do not enable this check box, only the COM number for the selected port will be changed to the COM
number listed in the drop-down list box. Enable this function if you want to configure the UPort’s serial ports
with sequential COM numbers.
Friendly Name
Setting
Factory Default
Necessity
1 to 20 characters
(E.g., UPort 2210)
Moxa UPort COM
Optional
Users can assign a Friendly name to each of the UPort 2000’s serial ports. The friendly name gives users an
easy way to identify the serial devices connected to the UPort’s serial ports. If you enable set the change to
all ports and then click OK, the same friendly name will be assigned to all ports.
Fast Flush
Setting
Factory Default
Necessity
Enable/Disable
Enable
Required
The Fast Flush setting is designed for applications that call the Win32 PurgeComm() function before reading
or writing data. If Fast Flush is not enabled, then instead of just flushing the local buffer, the UPort’s driver will
query the UPort’s firmware repeatedly in a short period of time to make sure that no data is queued in the
UPort’s firmware buffer. For this reason, you may find that your PC’s native COM ports respond much more
quickly when making PurgeComm() function calls compared to the UPort’s serial ports. In this case, enable
Fast Flush (enabled by default) to speed up the reaction of the UPort’s serial ports.
