how to convert serial port to USB port?

hi there,

having a problem...
i need to convert from serial port to USB port?
as i had a program that read the COM port rather than USB port..

may i know how to differentiate the different USB port(is there name for it, eg for COM port is COM1,COM2..what about USB port??)...

Hi TPoly,
So you don't have any COM ports on your machine?
You can buy a USB Serial adapter. It plugs into the USB port and has a normal serial port on the other end. Then when it is plugged in the computer registers an additional serial port which your software can just use like any other.

Here is an example of such a device - many can be found on the net + explanation on how translation from USB to COM is done. Inj any case, what you'll have is a Virtual COM (VCOM) with COM3,COM4....etc. addresses, so your programs can access those ports in any time.

Sorry, forgot to put the link to example device site:
Hi Tpoly ,

Title: how to convert serial port to USB port?  (SERIAL - USB)

I havn't seen it done - but if you're talking USB - SERIAL , the responses listed here are spot on.
** I've noticed with USB-SERIAL bridges that the baud rate can be a bit fiddly setting up (most seem to work best @ 9600) , other problems can arise  if the software you're using needs to access a physical hardware address -   the only fix then (if you're using a laptop) is to get a  PCMCIA - SERIAL. (which offers a true hardware port) but PCMCIA-SERIAL costs about 5 times as much.
