In Unix and Linux systems access to the serial port is restricted. This means that either there is a program to lock the port with super-user privileges, or the permissions of the port are changed to give read/write access to a group of users or to all users. The latter is dangerous in that it creates security problems. In any case super-user privileges are needed to install the software or to give access to the serial port group.
The installation is done as with other such packages and there is no need for configuration. Users of GPSMan must belong to the group that owns the serial port to be used (normally dialout).
The program is launched by calling gpsman that may have as single argument the path to the serial port device.
After unpacking the files, using tar xzvf gpsman-5.4.2.tgz, the
GPSMan main file,
gpsman.tcl, should be edited for
configuration (see below) and put where it can be
executed. The other GPSMan files should go into the directory whose
path is given in the beginning of gpsman.tcl.
The package includes a file
gpsman.sh in the util
directory that is a shell script to
call gpsman.tcl with no need to give the serial port as
argument. This file should be edited for configuration and placed
where its can be executed.
A directory aux is created that contains the source of
utilities to lock and set the serial port. These utilities, that need
the liblockdev library, must be run with super-user
privileges. One is gpsman
that tries to lock the serial port and calls the Tcl/Tk program
gpsman.tcl passing the path
of the serial port to it as an argument. The other one is
gpsman-config that
sets the path of the serial port to be used. This path is stored in the file
/etc/gpsman.
After unpacking the gpsman-5.4.2.zip archive the
GPSMan main file,
gpsman.tcl, should be edited for
configuration (see below) and put where it can be
executed. The other GPSMan files should go into the directory whose
path is given in the beginning of
gpsman.tcl.
