How to install PC/X non-intelligent board under SCO Xenix/Unix * Driver is built into SCO. * Only boards supported are PC/4 & PC/8 - PC/16 is not supported * No other COM port or peripheral can share an IRQ with the DigiBoard * PS/2 Models 25 & 30 can only be setup as COM2.

Log on to the console, and type at the prompt mkdev serial (press return) 2. The first screen you will see is: The following cards are currently configured: (any previous installed serial board will be listed) i) install a new serial board. r) remove an existing board. q) quit Please enter your choice (i/r/q) > (usually you are picking i) 3. Serial Board Installation You would like to install a: 1. 1 port 2. 2 port 3. 4 port - if using PC/4 4. 5 port 5. 8 port - if using PC/8 6. 16 port - NOT SUPPORTED Select an option or enter 'q' to quit: select 3 or 5 The card is configured as: 1. COM1 2. COM2 3. COM3 (not supported) 4. COM4 (not supported) Select an option or enter 'q' to quit: select 1 or 2 4. Which card do you have (the following are supported) ? (Pick you DigiBoard type from list shown on screen) 5. Please enter the baud rate to be used on the modem devices: (pick highest baud supported by modem, example 9600) 6. The following /etc/gettydefs entries support 9600 baud lines 1. 9600 2. console 3. 9600H 4. o 5. 6 6. m 7. sc_m Then you should see the following messages: System files successfully updated. The following standard serial devices have been installed. (you will see a list of device names that will be created) You must create a new kernel to effect the driver change you specified. Do you wish to create a new kernel now? (y/n) (answer yes to this question, then reboot system) 7. The systems will create devices in the /dev directory for the DigiBoard PC/X, they will be created after system reboot. Board setup Standard devices Modem control devices COM 1 /dev/tty1a-tty1h /dev/tty1A-tty1H COM 2 /dev/tty2a-tty2h /dev/tty2A-tty2H Standard devices are usually terminals and printers. These ports must have a null modem cable or null modem adapter between the DigiBoard and the peripheral to work. The basic cabling for x/on x/off flow control is TxD and RxD crossed and signal ground straight through. Check your DigiBoard hardware manual for proper cabling, if unsure. Modem control devices are usually modems. These ports must have carrier detect high before the port will open. The cabling usually has signal going straight from DigiBoard to modem. Check your DigiBoard manual for proper cabling, if you have any questions. 8. How to enable standard port to get a login. enable /dev/portname example: enable /dev/tty1a Make sure your terminal matches the setup in your inittab file for SCO Unix or ttys for SCO Xenix. The default is 9600 baud 8 bits no-parity 1 stop bit.
