-#### 18.1.4.1 Making Device Special Files

-A shell script called `MAKEDEV` in the `/dev` directory manages the device special files. To use `MAKEDEV` to make dial-up device special files for `COM1` (port 0), `cd` to `/dev` and issue the command `MAKEDEV ttyd0`. Likewise, to make dial-up device special files for `COM2` (port 1), use `MAKEDEV ttyd1`.

-`MAKEDEV` not only creates the `/dev/ttyd`***N****** device special files, but also the `/dev/cuaa`***N******, `/dev/cuaia`***N******, `/dev/cuala`***N******, `/dev/ttyld`***N******, and `/dev/ttyid`***N****** nodes.

-After making new device special files, be sure to check the permissions on the files (especially the `/dev/cua*` files) to make sure that only users who should have access to those device special files can read and write on them -- you probably do not want to allow your average user to use your modems to dial-out. The default permissions on the `/dev/cua*` files should be sufficient:

 The idea here is to allow people to set up dedicated servers that require no graphics hardware or attached keyboards. Unfortunately, while most systems will let you boot without a keyboard, there are quite a few that will not let you boot without a graphics adapter. Machines with AMI BIOSes can be configured to boot with no graphics adapter installed simply by changing the ***graphics adapter*** setting in the CMOS configuration to ***Not installed.***

-However, many machines do not support this option and will refuse to boot if you have no display hardware in the system. With these machines, you will have to leave some kind of graphics card plugged in, (even if it is just a junky mono board) although you will not have to attach a monitor. You might also try installing an AMI BIOS.
