Hello! I am writing this post over a serial line. This is no ordinary serial line. I’m in the garage on my laptop. My laptop is connected to a USB-to-serial device. That device is then connected to an xBee zigbee module. I’ve got a very similar setup on my PC in my room. The zigbee transceiver on my laptop is just out of range of the transceiver on my PC. There is a third xBee module sitting in our lounge. It has it’s receive line connected to it’s transmit line.
I’ve then got a slip connection running over that serial connection, which is 9600 bps. It’s also incredibly latent:
[rob@prefect ~]$ ping -c 5 192.168.2.1 PING 192.168.2.1 (192.168.2.1) 56(84) bytes of data. 64 bytes from 192.168.2.1: icmp_seq=1 ttl=64 time=596 ms 64 bytes from 192.168.2.1: icmp_seq=2 ttl=64 time=596 ms 64 bytes from 192.168.2.1: icmp_seq=3 ttl=64 time=598 ms 64 bytes from 192.168.2.1: icmp_seq=4 ttl=64 time=595 ms 64 bytes from 192.168.2.1: icmp_seq=5 ttl=64 time=596 ms --- 192.168.2.1 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 4000ms rtt min/avg/max/mdev = 595.813/596.868/598.809/1.156 ms [rob@prefect ~]$
These xBee modules are cool!

Rob, you need to sort out this blog, it’s a disgrace. I have three problems with it (in increasing order of seriousness)
(a) If you go into one of the archives, you can’t get back to the main page – i.e. get yourself a HOME button!
(b) In your discussion of fedora/ubuntu, you seemed to overlook the fact that a fedora is actually a hat and so can be “worn” by your rooster. This doesn’t work with ubuntu which sounds like an Australian musical instrument.
(c) I don’t understand any of any of the posts.
I hope you’ll be sorting out all of these issues promptly. Thanks,
Alison
Answers/Solutions:
(a) One can click on the word “xGoat” at the top left to go home. Possibly unintuitive. In my defence, I did not design this template. One day, when I live in a land with fairies and kittens, I shall be at one with the website.
(b) I wholeheartedly agree with your argument. Fedora rules.
(c) Hmmm. I’m fairly sure no-one does. Perhaps a (partial) electronics degree would help you understand. Perhaps I should allow people who are reading it to select their insanity level and then it could prune the text according to preference.
Rob.
