Modifying a Device Driver's Settings (WNT/2000/XP)
Use the following syntax to change settings of a device:
mtcfg <port-name> <setting1> [<setting2> [<setting3>...]]
each of the settings is specified as
name=value
if value contains spaces, the whole name=value string should be enclosed in quotes (not
just the value), e.g., to specify the string “MT-85 on COM1” as the friendly name for
COM5 with a baud rate of 9600 bps, use the following syntax:
mtcfg COM5 ”FriendlyName=MT-85 on COM1” baud=9600
Following is a list of common settings that can be changed for a device. Most settings
have a default value and may be missing when the list of settings is requested for a device
(e.g., by typing “MTCFG COM5”).
Name Use
baud (optional, used for serial devices only) device’s baud rate, specified as
an integer (e.g., 9600)
parity (optional, used for serial devices only) an integer specifying the parity
used by the device: use -1, 0, 1, 2, or 3 for None, Even, Odd, Space
and Mark parity respectively.
datasize (optional, used for serial devices only) specifies the device’s serial
word size in bits: 7 or 8.
stopbits (optional, used for serial devices only) stop bits to use on
transmission: 1 or 2.
UsePort the serial port to which the device is connected. Must specify a valid
standard serial port (or a port that is 100% compatible with a standard
serial port).
FriendlyName (optional) alternative name for the device. If specified, the device may
be opened from user mode using this name (the prefix \\.\ must be
added to the name. For example if FriendlyName=Port-powered swipe
reader, this device can be opened as “\\.\Port-powered swipe reader”)
EnableFDP (optional) Enable Flexible Data Parsing. Set this to 1 to enable data
parsing and to 0 to disable data parsing.
PortName Specifies the port name under which the device is visible to user-mode
applications. Modifying this setting also changes the name used to
refer to this device when using the MTCFG utility, e.g., if
mtcfg COM5 PortName=COM8
is executed, the device that was COM5, must be referred to as COM8
in any subsequent invocations of MTCFG. This setting is treated
specially by MTCFG−it will validate the port name and make sure that
it is not used by other MagTek devices before making the change.
Device settings other than the ones listed above should not be modified without carefully
reviewing the driver’s engineering documentation for the specific device model.
