Are there any tricks to getting Prompt working correctly? Ctrl seems to work good, at least the keys I tried (Ctrl-A/E/N/P/K/T). When connecting to a Linux box, I can get some of meta keys to kinda work, but most of them do unexpected things. When connecting to an OS X box, option just spits out special characters. Prompt doesn't appear to have any configuration option for what type of terminal emulation, so I guess my only options are to configure the shell I am connecting to. I just tried the latest versions of both Prompt and iSSH on iOS 5 on an iPhone 3GS. Prompt is at least a big improvement over iSSH in this area, but, unless I can figure out how to get it to work better, it is definitely not something I'd be comfortably using for Emacs.
