You need a terminal to do input. fbterminal is one that provides what 
you need. It does not work from the serial line out of the box as far as 
I know.

Please have a look at the x86-fb.* example in l4/conf/examples and 
start the client using the same method.
This will allow it to receive keyboard input. Instead of the 
ex_spectrum... example use fbterminal to start with mag using (for 
example) the following lines:

local c = { fb = mag_caps.svc:create(L4.Proto.Goos, "g=800x600"),
             term = l:new_channel():svr()
};
l:start({ caps = c }, "rom/fbterminal");

And then start the clntsrv-client in the terminal using (again, for 
example):

l:startv({ caps = { calc_server = calc_server},
             log = c.term:m("ro")
           }, "rom/ex_clntsrv-client");
