The program is just waiting for data over a TCP socket. I am using a
simulator program on another computer to send the data at configurable
intervals. I don't think a receiving and displaying a line with about
60 characters every 5 seconds over a 100 Mbits LAN would need a wait
(P4 3.0 GHz laptop).  I'll try it anyway, though. I also forgot to add
that I am using Gambas2-1.9.47, with the qt component, in case this is
relevant.
