Help reqd:USB to Serial

Hello
My PC have only one serial port,as usual!.Can I have one more serial port like USb to Serial or by some means?
can anybody suggest the possibilities.
My intention is to have one port used for ISP of uC's and at the same time use other port for testing serial communication of the same controller.Then during development physical removel of the port connectors could be avoided.
Please suggest

USB-to-serial adapters don't always work nicely with electronics.

Assuming you have a desktop/tower PC, not a laptop, you can buy a serial card that plugs inside - these are pretty standard.

For instance:

use a USB to serial convertor, the driver will emulate the Rs-232. Once the device connected to PC, the USB is transperant to you and you will found an additional com port in control panel. I have experienced on this for Rabbit ISP, it work stable as RS-232. The other advantange is most convertor able to run up to 384k baud rate.

U may use the hub with bridge. It can extend the serial from one to many.

Go to Cypress.com and search for USB Serial Reference Design with EZ-USB chips.

Ok, but if I use a FT2232BM chip, can I put this in a device and use this device like a host? or the FTDI chips can only use in a regular device?

I am using the config you describe ! 8O

I use my PC serial port for ICSP and a serial (usb-serial) port for debugging my program. And It works fine !

Should work fine. I connected a siemens module to my one port and debug my program through the other port using a usb to serial cable.
