Settings Stored in the Windows Registry

The WinMux2k driver parameters are located in the registry path

HKLM\System\CurrentControlSet\Enum\Root\winmux\000X\Device Parameters.

X is the number of the device instance.

All values listed below will be created during the installation of the WinMux2k driver. The settings are provided
by the winmux2k.inf file. If you want to write your own preferences to the Registry you can edit the inf file before
installing the driver.

Value

Data (Example)

Properties

BasePort

COM1

The physical serial port that connects the module to the PC.

BaudRate

115200

Baud rate used on the physical port.

BaudRateString

AT+IPR=115200

This string is used to set the module to the given baud rate.

Note: This string must contain the same value as the
BaudRate value.

If you select a higher baud rate be sure it is supported by the
module. For details see

[3]

.

ModemInit

AT
AT&S0
AT\Q3
AT+ICF=3
AT+CMUX=0

This multi-string value contains several AT commands
which are used to switch the module to multiplexer mode.
Possible ERROR codes resulting from unsupported com-
mands are ignored by the WinMux2k initialization sequence.

RequestTimeout

2000

Timeout value used only during the initialization of the mod-
ule. 2000 is the maximum number of milliseconds the mod-
ule can take to respond to AT requests.

VirtPort1

COM10

Name of the first virtual port. Each virtual port must have a
unique name. Otherwise the driver will fail to start up.

VirtPort2

COM11

See VirtPort1

VirtPort3

COM12

See VirtPort1

VirtualChannels

3

Number of Virtual Channels visible as COM ports. The
WinMux2k driver supports up to 3 virtual ports. The number
of VirtualChannels must be less or equal to TotalChannels.

TotalChannels

3

If the number of TotalChannels is greater than VirtualChan-
nels and no VirtPortX value for additional channels is
defined, these additional ports are not visible as COM ports.
They can be accessed by the link named
SERMUX_CONTROL_PREFIX defined in sermux_i.h. This
allows to hide virtual ports to the user. Each physical port
can have one hidden port.

WakeUpTime

4000

Timeout during module initialization. The timeout takes
effect only when the driver tries to restart the module from
Power Down or to wake it up from SLEEP mode
AT+CFUN=0. The time is given in milliseconds.

PowerCmdPort

3

This virtual channel is used to send the power down com-
mands to the module. The data state on this channel may be
disturbed during power down and cannot be reconstructed
by the driver.
