A000030: If you use the serial port for printing or plotting you need to put the DOS MODE command into your AUTOEXEC.BAT file to set up the serial port before you run DANCAD3D.COM (tm) (if DOS MODE is in your AUTOEXEC.BAT file your serial port will be automatically set up each time you turn your computer on.) Some plotters require a "NUL MODEM" type serial port cable to operate.

Yes, because the SignaLink doesn't require a connection to the computer's serial port! Unlike other interfaces, the SignaLink never requires a serial port connection. This is particularly handy if your computer doesn't happen to have one! In addition to simplifying your installation, this feature also reduces the likelihood of the computer's RF noise getting into your radio. It also eliminates serial port related transmit problems that plague other interfaces.

If the HTMLCompiler doesn't see the Amulet Module, the compiler will display the " Serial port timed out" error message. Recheck the DIP switch settings, the serial cable connections and the power connections, and then try again. You might also try a different baud rate. If the selected serial port is already open and in use by another application, the HTMLCompiler will abort the FLASH programming cycle and display the " Port is in use" error message.

Your keyboard will still work if you unplug your Reader from the serial port. However, the Reader in the Reader Keyboard will not communicate with the PC if the serial plug is disconnected. If you unplug the Reader or Reader Keyboard from the keyboard port, your keyboard will not work.

The serial port should be located on the back of your computer. An example of a serial port image is provided here.

A - You can add a Serial Board or a Multi-Port Board (with serial ports) to add more serial ports to your PC which cost as very little . Or you could use a (Serial) Switch box to connect two devices to one serial port.

A#8.15: This is usually caused by serial port configuration problems. Common symptoms may be: % copycat .ttyco .ttya Error opening tty .ttya, aborting. or % /usr/sbin/getty 8bit.38400 .ttya getty: .ttya: I/O error The first thing to check is that the following GNO serial port drivers exist: /dev/modem /dev/printer Next, ensure the following two lines are in your /etc/tty.config file, and that they are uncommented: modem 2 .ttya printer 1 .

A#8.9: This answer describes hooking up a terminal to the printer port. Hooking one up to the modem port will be similar except that .ttya should be used instead of .ttyb. On the hardware side, you will need a mini DIN 8 to DB25 printer cable. This should be connected from the IIgs' printer port to the port on the terminal that would normally be hooked to a modem. Next, you have to run a getty(8) over the printer port. Add this line to your /etc/inittab file: pp:23478:rest::/usr/sbin/getty 8bit.

The issue is how Windows deals with the joystick - if you can calibrate / test the joystick via the joystick icon (Game Controllers / Gaming Options) in Control panel, then "Joystick-To-Mouse" will work. If the device actually plugs into the serial port (and NOT the game port), then it may possibly / or with the right drivers from the manufacturer, act like a mouse. Primarily "Joystick-To-Mouse" expects a standard game port joystick or USB joystick.

With v1.87 of the controlling software if you choose 'Direct Serial', to enable the serial port under the emulator, and then quit the emulator it doesn't correctly release the serial port back to RISC OS. However a temporary patch is to uncomment the very last line of the !PC486.!Run file. Then you should find control of the serial port returned to RISC OS after you have finished with the emulator. As of v1.91 this has been fixed and the serial port will be released properly.

You can't. Do not try to use a PS/2? to serial adapter or any other adapter to connect the ergonomic mouse to a serial port. It won't work and may harm your computer.

The printer should print the directory listing in 40-column mode. To check the lines, do a regular directory listing:

I've connected the USB to Serial adapter but it's on Com Port 5 (or higher) and your software only has Ports 1-4. This issue applies to the c\temp software only. This has been resolved with the new version of the MDAS-Pro software. If you do not have a copy of this software, please contact us.

Some unnamed clone cards have also been known to work, especially those that claim to be AST compatible. USB device support was added to FreeBSD 3.1. However, it is still in preliminary state and may not always work as of version 3.2. If you want to experiment with the USB keyboard support, follow the procedure described below. Add the following lines to your kernel configuration file, and rebuild the kernel.

For Unix, see a Usenet post by Mitch Chapman: http://groups.google.com/groups?selm=34A04430.CF9@ohioee.com

It's system-dependent. Under Unix, you typically open, read, and write a device file in /dev, and use the facilities of the terminal driver to adjust its characteristics. (See also questions 19.1 and 19.2.) Under MS-DOS, you can use the predefined stream stdaux, or a special file like COM1, or some primitive BIOS interrupts, or (if you require decent performance) any number of interrupt-driven serial I/O packages.

It allows the application to interface to the GPS receiver through the same interface (commands and logs) as an external controller would through a physical com port.

The serial port is a 9-pin D shaped connector, similar to the video connector except with less pins. Usually, there are two on a PC. One may possibly be in use by the mouse (mainly on older machines). They are also referred to as Com ports or Communications ports. They are identified in Windows as Com1, Com2 etc. Look in the device manager under "ports" and you will see if you have any set up - if not, you may have to enable them in you motherboard's bios via the CMOS setup utility.

Answer: Three serial ports are provided. One can be used for external control from a modem or other serial device. The other ports can connect to managed serial devices (such as routers, PCs, servers, or other RS-232 devices). Port 3 is the default control port. Ports 1 & 2 use the PC standard DTE pinout, with RXD on pin 2, and TXD on pin 3 of the male DB-9. Port 3 has TXD on pin 2, and RXD on pin 3 of the female DB-9. Port 3 offers hardware handshaking; ports 1 & 2 do not .
