I was watching the thing and got to the part where he said that he was using XON/XOFF flow control and thought that the guy’s Arduino RS-232 ASCII-to-Baudot-encoding thing could be made more efficient if he’d make the encoder use the RS-232 RTS/CTS lines instead of XON/XOFF encoding. Then I realized that he’s converting to 45.5 baud, and that at that speed, even his 9600 baud line — normally the chokepoint for people with modern hardware, you know, 1980s and on or so — is blisteringly fast and inefficiency at that point is irrelevant.
