I'd have to say that maybe you should do some serious proof reading. This lacks the professional appearance that I'd expect from a TR post. I'm not trying to flame you. I just feel that maybe you posted too quickly? Were you under some time constraint?
What?! I thought Macs were only "good for graphics"! You mean they can be put on a network as well?! That goes against the DNA of most IT departments.
I would also suggest ConceptDraw Pro. I've tried the trial versions a couple of times and it's on my short list of programs to buy...
What I do, since as you wrote Mac OS does not have a Serial Console application (like HyperTerminal on Windows), is open a Console window and type "screen /dev/tty.usbserial". When I'm done I press Ctrl +A and then K, which kills the session. I am sure you could create a shell script so that you need not type it. Also you could set the port speed to 4800 by doing a "screen /dev/tty.usbserial 4800" or by replacing the 4800 to some other speed to whatever your serial console supports.
Great picks, thank you Selena. One of my personal favorites is IPNetMonitorX (sustworks). This is a suite of 20 networking tools that are just too many to list; the two I use almost every day? Address Scan and WhoIs. Address Scan can ping sweep network spaces; WhoIs will automatically dig deep if you "start" with arin. Indispensable.
Even better than OmniGraffle is OmniFocus - has Mac/iPhone/iPad versions, which all sync to one pot of data. Indespensible.
