Mac OS X includes a free terminal, but it doesn’t support serial ports without some serious tinkering. And while I often use USB-to-RS-232 serial cables, I use a Bluetooth serial dongle a whole lot more. (I love Roving Networks’ little “FireFly,” aka RN-240, which uses AAA batteries to stay paired with my MacBook Pro.) This way I have fewer cables to trip over and in some cases I can even sit outside the noisy cable closet to do the initial configurations on switches and routers. ZTerm doesn’t emulate a ton of terminals (the VT100 family excepted), and it won’t talk to some odd devices, but for the most part it does its job and Mr. Alverson seems to be asking only for a donation if you like it.
