RS-232 support in PC Minix is part of the tty driver. The main advantage of this arrangement is that the serial port can be used for access to devices such as modems as well as external terminals connected to the system. An RS-232 device could be implemented independently from the tty driver. This appears to be much easier than changing the tty driver. Adding support for bitmap graphics would also require changes to the tty driver (already the biggest source file for Minix). The tty driver could get very, very ugly. Are there alternative solutions?
