Limitations and Bugs

QuickTerm does not understand any control codes, and will not emulate an ANSI or VT100 terminal. It does accept control code data as valid input, but does not display or otherwise act on unprintable characters. I looked into implementing this, but I don’t think it can be done easily without replacing the NSTextView that makes up the main window with a completely new control class. NSTextView (and its ancestor NSText) seem to be too focused on document-type data to be well adapted to this screen-based application.

QuickTerm only supports a single terminal window, so only one session can be active at a time.

No file transfer protocols are supported, although you could do a text transfer by copying from and pasting to the terminal window.

Preferences are not implemented. If you look at the source code, you’ll see that there is some commented-out code for adjusting the background and font colors. I didn’t finish the implementation.

QuickTerm will not disconnect if a data write is pending on the serial port when hardware flow control is enabled. It will disconnect after the write is done. If it never finishes, the app will hang and have to be force quit.
