------------ I. Hardware The serial port adapter I bought for $35 is called "KW-509B asynchronous communication adapter". It provides two RS-232C serial ports, configurable as either COM1, COM2, COM3, or COM4 with IRQ level of 2, 3, 4, or 5. Since I've already have COM1 with IRQ4 and COM2 with IRQ3 on my 386 machine, I configured the two ports as COM3 with IRQ5 and COM4 with IRQ2. II. Software The operating system I have is Interactive V/386 2.0.2. And the followings are the list of files that need to be edited and their modified contents. The information is interpersed throughout "AT&T UNIX V.3.2 Integrated Software Development Guide". /etc/conf/cf.d/mdevice asy Iocrwi iHct asy 0 3 1 4 -1 /etc/conf/init.d/asy 00:2345:respawn:/etc/getty /dev/tty00 9600 01:2345:respawn:/etc/getty /dev/tty01 9600 02:2345:respawn:/etc/getty /dev/tty02 9600 03:2345:respawn:/etc/getty /dev/tty03 9600 /etc/conf/node.d/asy asy tty00 c 0 asy tty01 c 1 asy tty02 c 2 asy tty03 c 3 asy ttyd0 c 16 asy ttyd1 c 17 asy ttyd2 c 18 asy ttyd3 c 19 /etc/conf/sdevice.d/asy asy Y 1 7 1 4 3f8 3ff 0 0 asy Y 1 7 1 3 2f8 2ff 0 0 asy Y 1 7 1 5 3e8 3ef 0 0 asy Y 1 7 1 9 2e8 2ef 0 0 Then execute 'kconfig' as 'root' to have 4 COM ports available for logins.
