This is experimental software and probably contains defects. It remains under development. When available, newer versions of tk545 will be made available for download at this web site.
mkdir /home/username/tk545
cd /home/username/tk545 gunzip tk545-1.4.tar.gz tar -xvf tk545-1.4.tarThis will create a new subdirectory, named tk545.1.4 and place the files there.
tk545=/home/username/tk545/tk545.1.4 export tk545To make the change permanent, you must add the two lines above to your shell's profile, e.g., /home/username/.bash_profile if you use the bash shell.
For example, I use /dev/ttyS1 as the serial port to connect the radio. If I type in a console window:
ls -l /dev/ttyS1the output shows the permissions:
crw-rw-rw- 1 root uucp 4, 65 Aug 15 06:40 /dev/ttyS1Notice that /dev/ttyS1 is readable and writeable by everyone (user, group, and others).
Login as root or run the su program to assume root privileges. Then, change the permissions and exit.
chmod ugo+rw /dev/ttyS1 exit
