Notebooks with serial ports are normally on the higher end of the scale, but those USB - RS232 ports works quite well. One note thought, if you need to use hyperterm, the coms port tends to change (some feature of the USB spec), so if the first connection on Port1 doesn't work, change to Port2, or whichever the USB drivers have assigned it. But it works well on routers and other serial devices. I want to think there's a PCMCIA version as well
