Yes on a modern computer you will need a USB to 9 pin RS232 converter or previously use the LPT parallel port.

com1,com2 com3


What are com1 com2 and com3?

COM1 and COM2 originally referred to the serial port interfaces on a PC. Now they can refer to any port, virtual or physical.


What system resources does COM3 use?

well COM1, COM2, COM3, and COM4 are sometimes configured as Serial Ports.


Why might you have a resource sharing problem if you install a serial port on both COM2 and COM4?

COM2 and COM4 use the same interrupt by default (IRQ3). The same is also true for COM1 and COM3 (IRQ4).

Can LPT Port be used as COM Port?

MODE LPTx=COMx Unfortunately MODE LPTx:=COMx redirects parallel printer output to a COMport, I've never seen any indication that it will work the other way. For example, to accommodate a 1200 baud serial printer on COM2 to a program that only has LPT1 output: MODE COM2:1200,n,8,1,p sets up the comport with continuous retry MODE LPT1:=COM2 redirects LPT1 output to COM2


How can you access a com port on a network from one PC to the next?

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.


What is the maximum number of serial ports for Windows XP?

There's no limit to the number of serial ports. The maximum number for the traditional ports is 2 (COM1/COM3 and COM2/COM4). Plus you can attach additional serial port adapters to a USB port, up to 127 per controller.


What is the interrupt request number for the serial port 2?

IRQ 3 is for COM2 and COM4 (serial ports). See related link.


How do you add com2 to the connection ports?

If your system only has one COM: port, you will have to physically add in a card or USB-RS232 serial adapter, and follow the installation instructions. If your system has 2 COM: ports, make sure that in the CMOS (BIOS) settings, that the port isn't disabled or assigned as an InfraRed port. Also, make sure that you physically have the connectors at the back of the unit available. Many motherboards offer COM2: only as an option, and it requires an optional (not included) cable that hooks to the motherboard.
