This application needs the users to access serial and/or parallel port

in RW mode, depends upon the programmer is used.

So, administrator have to add allowed users to uucp and/or lp groups.

To do this, type the following command line:

    useradd -G lp,uucp allowed_user

for each allowed_user you want to add.

And if a parallel port programmer is used, you need to load the ppdev module,

by typing the following command line:

    modprobe ppdev

If you want to use the SDCC Compiler with Piklab, you have to modify

the PATH for the whole system, not only for a single user.

So, you have to add the following:

    PATH=$PATH:/usr/libexec/sdcc

in /etc/profile, before the command line

    export PATH
