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.

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 RT/2127 software can not share the serial port with other active software. For example, if you have a PDA cradle normally connected to COM1: and the PDA software is active on COM1: you will receive an error from our software when attempting to use the port.

A. When attaching a PDA cradle to the serial (RS232) port, verify that the port assigned to your HotSync and/or ActiveSync software is Serial USB (COMx). The PA090 COM port assignment can be viewed by clicking START, SETTINGS, CONTROL PANEL, SYSTEM, clicking on the DEVICE MANAGER tab, clicking the "+" sign next to "Ports (COM & LPT) and looking for a "Serial on USB (COM#)" entry.

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).

Information on how to use the mwave sound card on an IBM ThinkPad laptop computer can be found in the file /usr/src/linux/Documentation/sound/mwave, which is part of the kernel source distribution (note that not all IBM ThinkPads use the MWAVE sound chip). Some old 8-bit SoundBlaster cards have no mixer circuitry. Some sound applications insist on being able to open the mixer device, and fail with these cards. Jens Werner (werner@bert.emv.ing.tu-bs.

If your computer does not have a serial port, it should have multiple USB ports. Connection to the computer is via the serial to USB cable included with the MiniStation (GWS-MINI-U). This is a common perception that is definitely incorrect. When you use a serial to USB cable, you also install drivers to make that USB connection look like a standard RS232 port within your computer. Your application software will be looking for a serial port (COM1, COM2, etc.) for data input.

This will depend on what type of system is in the classroom. The connection portion is essentially the same for either, so we will begin with that. First, take the VGA connector and connect into the monitor output on the rear panel of the Thinkpad. Next, take the 1/8" audio jack (this looks like a small headphone jack) and connect it to the Thinkpad's sound card (port on side of Thinkpad). Make sure that the control knob on the side of the cart is in the 'P.C.

Some laptop computers don't have serial ports, but they do usually have at least one USB port. There are a number of very inexpensive converter cables available. They use a device driver to create a serial port under windows operating system. The driver that comes with the converter cable must be compatible with your version of windows of course, and the USB ports must be functioning, both in hardware and in the operating system and in the drivers for the convertor cable.

COM connect is a bridging layer written by David Bradley to transparently support ActiveX automation inside of XPConnect. It works by mapping data types, querying type libraries and much more to seamlessly bring the two together. When the plugin is built with COM connect support, it exposes the IDispatch interface of the control through the plugin API and the COM connect layer transparent maps it into XPConnect. The upshot is that you can call directly methods on ActiveX objects from JavaScript.

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

Many new PCs (especially laptops) have USB ports but do not have the standard 9-pin serial ports found on older computers. This presents a problem because most of the GPS manufacturers don't make data cables that terminate with USB plugs. Unfortunately, we have noticed that the USB-Serial converters often cause computer crashes. We are working hard to resolve this problem.

No. The serial port and gameport are totally different. Even if you could find a physical adapter they would still not be compatible electronically.

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.

If you are running PC Access 4.20 or 4.30 in Windows 2000 or Windows XP, the Modem Wizard cannot read your modem settings from the Windows 2000 or Windows XP Registry. Use the instructions below to manually select your modem's COM Port. If you are running PC Access 4.20 or 4.30 in Windows 95/98/NT, the Modem Wizard may be unable to detect the correct COM Port on PCMCIA modems and some internal modem cards.

You will need to add a serial port to the computer to be able to connect it to a TNC. There are several companies making serial port adapters that connect to the computer through the USB port. Most require that the operating system in the computer be Windows 98 or later (or a Mac OS). Once that serial port has been connected to the computer and recognized by the operating system in the computer, it should be available for any Windows (or Mac) terminal program to use to communicate with the TNC.

ANSWER: You can use a standard 9-pin serial cable to go from a computer to a LC unit without needing an adapter. However, if you'd like to use cat5/network cable then you would need one RJ45-to-DB9 female for the computer side and one RJ45-to-DB9 male adpater for the LC side. If you would like to connect more than one LC unit to the computer in this manner simply use a RJ45 splitter in the line to provide more connections.

Yes, but since the voltage levels on the RS-232C serial port is ? 12V you have to use an interface circuit like
