You need to get a Bluetooth RS-232 dongle, which connects to serial RS-232 port and provides bluetooth connectivity. These are similar to USB bluetooth devices to some extent, but need a power source for the electronics circuitry (as you may be aware that USB ports have 5V power supply but RS-232 standard has no option for power supply on the connector). So Serial port to Bluetooth convertors will have either an inbuilt battery or a power supply connector to feed power. Here are examples : http://www.lemosint.com/scripts/bluetooth_parani_sd.asp

To download music to a mini speaker, first ensure that your speaker supports Bluetooth or has a USB port for direct connections. For Bluetooth speakers, pair your device (like a smartphone or tablet) with the speaker and play music directly from your music app. If the speaker has a USB port, you can transfer music files from your computer using a USB cable. Always refer to the speaker’s manual for specific instructions related to your model.
The speaker has a microUSB port, which I assume is for charging its internal battery. If that is the case any USB AC adapter and a USB to microUSB cable (see image) to connect them should work just fine.
In an RSTP-enabled network, the possible port roles for ports A, B, C, and D are Root Port, Designated Port, and Blocked Port. The Root Port is the port that provides the shortest path to the root bridge, while the Designated Port is the port on a network segment that has the lowest cost to the root bridge and is in the forwarding state. Any port that does not fulfill these roles may be placed in a Blocked state to prevent loops. The specific roles would depend on the network topology and the bridge IDs.
What kind of upgrade are you trying to do?, most upgrades are taken through the satellite stream. if your trying to change the fimware on the receiver then you would need a jtag and a serial cable, there are lots of websites that can give you the information you need and the schematics for building your own. Just Google jtag. Hope it helps. Karp.
Uganda is a landlocked country and does not have its own sea port. However, it relies on the ports of neighboring countries, primarily the Port of Mombasa in Kenya and the Port of Dar es Salaam in Tanzania, for maritime trade. Goods are transported via road and rail from these ports to Uganda. The country is working on improving its inland port facilities, such as the Port of Kampala on Lake Victoria, to enhance trade connectivity.
A com port can also be called a serial port.
RS-232 serial ports are far slower than USB ports. With very few exceptions, devices that use USB ports would be impractical to use on a serial port.
Yes on a modern computer you will need a USB to 9 pin RS232 converter or previously use the LPT parallel port.
The USB port, unless it is a Bluetooth mouse, then there is no port, it will connect via Bluetooth.
Serial port, this one, (http://en.wikipedia.org/wiki/Image:RS-232.jpeg) it is usually coloured green on modern computers.

Difference between Rs232 and RS485 is Only Distance RS232 is not for long or far distance .. but RS485 can be use for LONGEST distance ..RS232 is single ended communication where as RS485 is Differential communication.Max.no of receivers in RS232 is only ONE, whereas in RS485 is 32.Max.no of transmitters in RS232 is only ONE whereas in RS485 is 32.IN RS232 there is no pin to change from transmitter mode receiver mode. But, In RS485 have DE pin to set transmitter mode and RI to set receiver mode.
RS232 DB9 connectors Receives data serially from Pin No. 2 & Transmits data from Pin No.3.
No, infrared port uses IR radiation and bluetooth uses radio frequency radiation.
GPIB (general purpose interface bus) is a parallel port device. it can transmit more than one bit at a time. it is faster than rs 232 port. which is a serial port can transmit one bit at a time.the only disadvantage of GPIB or parallel port is it require more transmission bit so its transmission distance reduces.
A USB modem plugs into your USB port.A "normal" modem plugs into your RS232 port or your parallel port.
Assuming you meant 'doesn't have bluetooth - you can buy a bluetooth dongle - that plugs into a vacant USB port.
