105 (figuration of the utility, using a config file)
107 * Add single quote support for (old) command line parser

193 processing the receive buffers slower than the network controller

197 Change behaviour of NetLoop(): return -1 for errors, filesize
198 otherwise; return code 0 is valid an means no file loaded - in this
