Hi ,
You will have to install the driver for the USB device then you will be seing these additional ports as com3.com4 etc so you will be able to use them as any other com port.

Hi Vicky

I was looking at an adapter at dick smiths and it didnt appear to have drivers, but upon checking with the store they tell me it does. This is a better way to go than pcmcia card with multiple serial ports.

Cheers

While the many USB adapters seem to be easier to handle, we have had some bad experiences. Their stability is not always up to the task for industrial applications. This might not be an issue when you only use them to control your RS-232 lab equipment for manual experiments, but in our case we have fully automated lab systems running, where LabVIEW controls sometimes up to 8 serial devices and those applications are supposed to run day and night, if possible for many days in a row without interruption. With many of those noname USB-RS232 adapters we noticed various kind of problems. It could range from intermittent communication errors (which could be handled by additional code in our software to retry communication on such errors) to complete failure of the RS-232 port after some time, which could only got back online by unplugging and replugging the USB adapter.

For our purpose this was completely unacceptable and we ended up using ENET-RS232 devices instead which are working fine for months in a row.
