USB to serial adaptors allow you to use RS232 based hardware via a computer's USB port.
I bought SiteCom's USB to serial cable and it works perfectly with Linux:
- open a console
- attach the adaptor
- read the syslog using the command
dmesg
- in the syslog you will find some lines reading like
[51904.256210] usb 2-1.6: new full speed USB device number 8 using ehci_hcd [51904.341896] usb 2-1.6: New USB device found, idVendor=067b, idProduct=2303 [51904.341904] usb 2-1.6: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [51904.341909] usb 2-1.6: Product: USB-Serial Controller D [51904.341912] usb 2-1.6: Manufacturer: Prolific Technology Inc.

Testing with another computer
To test with another computer I connect the USB to serial adapter to my USB port, the other end I connect via a female-female cable to an older computer's com2 port. Then I issue on my computer
dd if=/dev/urandom of=/dev/ttyUSB0
on the other computer I use
dd if=/dev/ttyS1
And I can see how garbage is transmitted.
Using it with wine
To use your USB to serial adapter with wine, just link it as com1 to the dosdevices:
cd cd .wine/dosdevices ln -s /dev/ttyUSB0 com1
