Max is 119,000 bps (bits per second) A lot of them usually use 19,200 or 9,600 bps.

What is the difference of serial and parallel ports?
Serial ports only allow one device to send and one device to receive at a time, where a parallel port can send and receive data at the same time.
How does computer send data through serial port?

What is the difference between a serial port and a parallel port?
Parallel ports are easy to program and faster compared to the serial ports. But main disadvantage is it needs more number of transmission lines. Because of this reason parallel ports are not used in long distance communications. Let us know the basic difference between working of parallel port and serial port. In serial ports, there will be two data lines: One transmission and one receive line. To send a data in serial port, it has to be sent one bit after another with some extra bits like start bit, stop bit and parity bit to detect errors. But in parallel port, all the 8 bits of a byte will be sent to the port at a time and a indication will be sent in another line. There will be some data lines, some control and some handshaking lines in parallel port. If three bytes of data 01000101 10011100 10110011 is to be sent to the port, parallel port communication is faster then serial port.
What are the disadvantage of serial transmission?
Speed... a serial connection can only send one piece of data at a time. Parallel connections have multiple data 'channels' sending data simultaneously 0- which increases the data rate considerably.
What is the function of the serial port?
To send and receive data between computers or other electronic devices.
What is the minimum number of wires needed to send data over a serial comm Link layer?

What are the advantages and disadvantages of a serial port?
Having a serial port allows you to plug more stuff in you computer. i think The serial technology and the parallel technology are now old technology because of hardware like USB and Firewire. They are ports on the back of your computer. Serial ports transfers bits one at a time in a single file one bit at a time. Parallel ports transfers data 8 bits are a time across 8 wires. There are still serial ports on your computer, a serial port comes in 9 and 15 pins and is a male. Things that used to and sometimes still do connect to them are mice, external modems, PDAs and cameras. Parallel ports have 25 pins and is female. Most the time printers used to connect to parallel ports.The serial technology and the parallel technology are now old technology because of hardware like USB and Firewire.

USB ports are fast replacing traditional and ports because of their ability to transfer data quickly?
The Universal Serial Bus (USB) send the signal serially. This would be slower than handling the data in parallel. Modern advances in processing speed has made the USB as fast as older parallel ports. The main advantage of USB is ease of use and 'plugability'. You can attach peripheral devices without switching the computer off first. They are 'Hot Swapable'. There are only four contact pins on a USB socket. Two power and two data lines. This makes it simple, cheap and safe.
Discuss the differences between hubs repeaters bridges and switches?
A repeater amplifies a signal. It will also re-send the signal as a "clean" signal. A hub is a multiport repeater. It will send a signal it receives out, through all of its ports - except the port where it received the signal. Bridges and switches are more intelligent, in that they send data only to the destination - according to the MAC address. Bridges and switches are similar, but switches have more hardware optimization, allowing for fast switching of large volumes of data.
How do you redirect output to serialport?
The best way is to attach a serial port using device to the serial port of your computer and use your preferred program to send data to the device
Can a serial port send data over a longer distance than a parallel port?
Usually, because a serial port doesn't have to deal with the problem of signal skew that can jumble the data on a parallel port and gets worse proportional to distance.
