I'm thinking more along the lines of something running on a small processor such that the TT4 and T2s are based on. Most of these simple KISS devices don't use flow control, so the device would have ot be able to buffer a couple of packets from each port at a time. It'd probably require a real hardware UART.<o:p></o:p></p></div><div><p class=MsoNormal> <o:p></o:p></p></div><div><p class=MsoNormal>Any ideas?<o:p></o:p></p></div><div><p class=MsoNormal> <o:p></o:p></p></div><div><p class=MsoNormal>Additionally, it would sure be nice if the digipeaters kept up with the number of seconds the CD light was ON during a 10 minute period (_not_ number of sucessfull packet decodes), and published that number as network utilization telemetry along with their normal beacons. Note the utilization needs to be scaled up by approx 3x since 36% is considered the point of saturation in Aloha type networks.<o:p></o:p></p></div><div><p class=MsoNormal><br clear=all>Wes <o:p></o:p></p></div><div><p class=MsoNormal>---<br>The world needs more geniuses with humility because there are so few of us left.<o:p></o:p></p></div><p class=MsoNormal style='margin-bottom:12.0pt'><br><br>_______________________________________________<br>aprssig mailing list<br><a href="mailto:aprssig@tapr.org">aprssig@tapr.org</a><br><a href="https://www.tapr.org/cgi-bin/mailman/listinfo/aprssig" target="_blank">https://www.tapr.org/cgi-bin/mailman/listinfo/aprssig</a><o:p></o:p></p></div><p class=MsoNormal><br><br clear=all><br>-- <br>Tyler Griffiths<br>N7UWX<br><br>See where I am:<br><a href="http://map.findu.com/n7uwx-12">http://map.findu.com/n7uwx-12</a><o:p></o:p></p></div></div></div></div></body></html>
