There generally r 2 com ports, com1 and com2. They are RS232 ports which r serial ports.one way to communicate between 2 PCs is to use a software called hyperterminal..its there in evry computer.( accessories-> communication tools). if not u can also install it. u can find more information on it online..in case..1> u can either use an RS232 to IR converter device connected to the respective ports of both the comps to communicate.u'l be usin IR communication in dis case.2> u can connect a cable between these two ports of both the comps( female-female...as RS232 is a male port).but ure comps wud need to b in close proximity for a physical connection like dis.
u can get back to me for any further clarification on the same.
A com port can also be called a serial port.
how many ports does com port have
A com port is the old type of serial port on a PC. They are numbered, and some PCs had two or more. Someone might use com port one for a mouse and com port two for a modem.
Use the "change port" command (without the quotes, of course) to change the port you're deciding to map to somewhere else. First, to display the current com port mappings, you can use change port / query Then, to change a port, type change [old com port]=[new com port] NOTE: Change the text in the brackets to the actual com port, making sure to use keyword "COM," again without the quotes, and in the example, without the brackets Here's an example: change port COM2=COM4 Finally, to delete a COM port listing, use the following format: change port /d [COM PORT] Here's an example of deleting a COM port listing: change port /d COM8 Hope this helps!
Communication Port.
COM 1 means SERIAL port number 1
COM port is used to configure a router but you can also get a COM port to USB port adapter which can configure a router using a USB port.
Net is short for network & com or comm is short for communication.
Com port
Serial Port
Your computer might not necessarily have a com port at all. A com port is just an older style serial port. USB ports have replaced com ports for the most part. If you have any com ports, they would be on the back of the computer. They would be male (pins sticking out), and have 9 or 25 pins. If there is a 25-pin female D-socket, that would be a parallel port.
Rollover cable is used.
