38
39 # apt-get install gcapsd
40
41 Verify that the systemd unit is running.

55
56 # apt-get remove gcapsd
57
58 ##Serial Ports and USB
59 If access to the serial ports or USB (e.g. DMC-4103) is desired through gclib, the following will provide steps to join the correct access group. If using USB, be sure the controller is powered and the usb is plugged in before beginning.
60
61 ###Determine group with access
62
63 $ ls -l /dev/ttyUSB* /dev/ttyS*
64 crw-rw----. 1 root dialout 4, 64 Mar 3 16:39 /dev/ttyS0
65 crw-rw----. 1 root dialout 4, 65 Mar 3 16:39 /dev/ttyS1
66 crw-rw----. 1 root dialout 4, 66 Mar 3 16:39 /dev/ttyS2
67 crw-rw----. 1 root dialout 4, 67 Mar 3 16:39 /dev/ttyS3
68 crw-rw----. 1 root dialout 188, 0 Mar 6 11:08 /dev/ttyUSB0
69
70 In the above listing, **dialout** is the group that needs to be joined. **uucp** is another common group that may be listed.
71
72 ###Add the desired *username* to the group.
73
74 $ sudo gpasswd -a username dialout
75 [sudo] password for username:
76 Adding user username to group dialout
77
78 Log out and back in for change to take effect.
79
80 $ groups
81 username wheel dialout
82
83 gclib can now connect to serial and usb devices from user *username*.
84
85 ##PCI Controllers
86 If using a Galil PCI controller, the PCI driver must be installed.
87
88 ###Extract source and build driver
89
90 $ tar -xf /usr/share/doc/gclib/src/gclib_pci.tar.gz
91 $ make
92
93 ###Copy module and add to kernel
94
95 $ sudo cp galilpci.ko /lib/modules/$(uname -r)
96 $ sudo depmod
97 $ sudo modprobe galilpci
98
99 ###Add galil group for access to PCI
100
101 $ sudo groupadd -f -K GID_MIN=100 -K GID_MAX=499 galil
102 $ sudo cp 90-galilpci.rules /etc/udev/rules.d/
103 $ sudo udevadm control --reload-rules
104 $ sudo udevadm trigger
105 $ sudo usermod -a -G galil username #exchange "username" with actual user's name
106
107 Logout and back in. The PCI hardware is now available for access.
108
109 $ ls -l /dev/galil*
110 crw-rw---- 1 root galil 10, 56 Jun 9 11:07 /dev/galilpci0
111 $ echo -e "\x12\x16\r" > /dev/galilpci0
