@b0rk Nope! Unix has always used "character" terminals that contained no local editing logic, just depending on the host to do everything. IBM mainframes and similar systems tended toward "block mode" terminals like the 3270, where the host would transmit an entire form to be filled out remotely, and then when the user pressed "send" it would get transmitted to the host. This was done because interrupts were slow and expensive so you didn't want to take one for every key pressed on the terminal.
