.SH NAME
eegdev-open-options - Device configuration format specification
.SH DESCRIPTION
.SS "Syntax of the configuration string"
.LP
The device configuration string should follow the syntax:
.LP
.ce
device[[|option1|value1]...[|optionN|valueN]]
.LP
If the specified device does not support a certain pair of option|value,
this will be silently ignored by the opening function. \fIdevice\fP should
be the name of a eegdev plugin or \fBany\fP. In the later case, it will try
to open one of the devices supported by the installed plugins.
.SS "Syntax of the configuration files"
.LP
The configuration files are made of statements (at most one per line)
following this syntax (whitespace are ignored):
.ce
option = value
.LP
Comments are preceded by the '#' character:
.sp
.in +4n
.nf
# comment line 1
# comment line 2
option = value #comment2
.fi
.in
.SH FILES
.IP "/etc/eegdev/eegdev.conf" 4
.PD

.IP "/etc/eegdev/<plugin>.conf" 4

(default sampling rate):
.ce

Any supported type of device but should have the serial number UB-2009.10.06
if it is a gTec system:
