Serial

I occasionally need to login to embedded Linux devices over serial connections. One frustrating thing about using a serial login is that programs running on the remote device don't know the window size of my local terminal emulator, so 80x24 is usually assumed even if I've resized my xterm to be much bigger (or even full screen!). Most network remote login protocols, such as ssh and telnet, use protocol features to communicate window change events transparently. Unfortunately, there is no such facility for serial logins, because there is no protocol.
