Where can PCI serial port drivers be downloaded from?
There are a variety of download locations from PCI serial port drivers. The safest and most reliable location would be from the manufacturer's website. It is recommended to find out the model number prior to trying to find the driver.
How do you redirect a serial port to output out of the parallel port?
You don't. If you are wanting to plug something into the serial port, and it is the same size as the parallel port (it isn't a parallel port, it's a different plug for the serial), use an adaptor. I'm in the same problem. I have a laptop and a program that uses com1 and need to redirect serial communication (com1) to a parallel port since the laptop doesn't have a serial port. i have an adapter for parallel to serial connections but need to remap com1. your can redirect lpt1 outputs with mode lpt1=com1 but not the other way round. If the laptop has usb just grab a USB to Serial Adaptor. Am in the same boot. A Point of Sales app need to be connected via a com port for Receipt Printing... The Printer is a ESC/POS Printer but has a Parallel Connection... Works fine under Windows, but not in the POS App. What is needed is some sort of Virtual COM Port to Capture the Outputs and Redirect it the a Physical LPT Port. In doesn't sound hard, yet no ones don't it...
Which port is associated with ttyS0?

How can you link RS232 serial data on COM1 to output on COM2?
Yes on a modern computer you will need a USB to 9 pin RS232 converter or previously use the LPT parallel port.
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).
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.
Can you redirect data sent to a printer parallel port to a USB port?
Yes. Use a USB to serial converter. The converted port will act like a normal comport. Even the name. Example of a USB to serial converter: http://www.newegg.com/Product/Product.aspx?Item=N82E16812240005 When sending data to one of your I/O devices the determining factor to where it goes is the drivers installed for the device. Perhaps you are using some sort of serial/USB adapter, in this case if the drivers installed don't support a USB port you will need to update them. If such drivers exist for your device you will probably find them at the manufacture's website. if you have the right connection to the usb port it will redirect data
What is COM1 used for?
COM1 is seldom used for anything these days, and may not even be mapped to a physical device on newer systems. Its primary purpose is/was to serve as a communications port, either to an internal or external modem, or as a connection into a mainframe computer. It has also seen some use as a general purpose expansion port and been used to attach mice, printers, and cameras to a computer.
