A serial port and a COM port, while closely related, are not the same. A serial port is a physical connection on the computer where a serial communications device, such as the PS-6155 dock station or a modem, attaches to the computer. Most computers have several serial ports (for the mouse and modem) and one parallel port (for the printer).

Q. I've tried to connect my 2100 with 8210 cable and nothing happens. Your program doesn't detect my phone.

The IBM ThinkPad also has a IrDA port that can collide with your serial/COM port. The best way to solve this problem is to disable the IrDA port. This can be done in the Device Manager (varies per operating system version). While you're there, verify that the serial/COM port is enabled. When asked, reboot the PC. This will re-enable the serial/COM port. After the computer reboots, return to the Device Manager and determine which port number the serial/COM is now on.

The RS 232 cable for the unit uses two conductors and a shield. Pins two and three are the data with pin five being the shield.

Yes. Under Windows 95/98/Me two port cards (DSP-100) can be installed to COM1 and COM3, COM 2 and COM 4 or any continuous block above COM 4 (COM 5 & 6, COM 6 & 7, etc.). Under Windows 95/98/Me Four port serial PCMCIA cards (QSP-100) MAY NOT be installed in COM 1 -COM 4. By default they will be installed in the lowest available continuous block above COM4. However, you may choose the continuous address block to which the ports are assigned. For example, COM 5,6,7 & 8; COM 6,7,8 & 9, etc.

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.

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

The easiest way to always keep the same COM port assignments is to always plug the unit into the same USB port. However, you can always reassign COM ports using the technique described above. No. Port properties can only be altered from the Device Manager window. Attempts to access these properties from another software program will generate an error message box that refers the user to the device manager.

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 .

Click on the Fax menu item from the top of the application , click on the Close sub-menu, select the port and close it. I have faxed to two different fax machines and both spit out a 1/4 sheet of solid black, no matter how I change the setup of Impact ColorFax. The problem is your SoftK56 PCI Modem(M)! Most likely the modem driver is old! The problem is your SoftK56 PCI Modem(M)! Most likely the modem driver is old! You have a software modem.

When the battery is completed drained, the unique pairing ID is lost. Please delete the Bluetooth GPS shortcut and

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.
