If you do not find what you want here, check into the Terminal and Dialup sections of the handbook. - - - <p> - The <tt/ttydX/ (or <tt/cuaaX/) device is the regular device - you will want to open for your applications. When a process opens - the device, it will have a default set of terminal I/O settings. - You can see these settings with the command - <verb> - stty -a -f /dev/ttyd1 - </verb> - - When you change the settings to this device, the settings are in - effect until the device is closed. When it is reopened, it goes - back to the default set. To make changes to the default set, you - can open and adjust the settings of the ``initial state'' device. - For example, to turn on <tt/CLOCAL/ mode, 8 bits, and - <tt>XON/XOFF</tt> flow control by default for ttyd5, do: - <verb> - stty -f /dev/ttyid5 clocal cs8 ixon ixoff - </verb> - - A good place to do this is in <tt>/etc/rc.serial</tt>. Now, an - application will have these settings by default when it opens - <tt/ttyd5/. It can still change these settings to its liking, - though. - - You can also prevent certain settings from being changed by an - application by making adjustments to the ``lock state'' device. - For example, to lock the speed of <tt/ttyd5/ to 57600 bps, do - <verb> - stty -f /dev/ttyld5 57600 - </verb> - - Now, an application that opens <tt/ttyd5/ and tries to change the - speed of the port will be stuck with 57600 bps. - - Naturally, you should make the initial state and lock state - devices writable only by <tt/root/. The <tt/MAKEDEV/ script does - <bf/NOT/ do this when it creates the device entries. |
