How to reset serial device from shell?

Hello, I have a Linux box with a bunch of plug-in cards that are configured as serial devices (ttyUSB and ttyS). Sometimes these devices appear to get stuck. I would like to know if there is a command I can run from the Linux shell that will "reset" or "restart" a particular one (or more) of these devices. If all else fails, rebooting the server usually brings them back to life but I would prefer to have a less disruptive option.

Thanks!

stty would be the most standard tool for managing serial ports. If you really mean devices that are attached to serial ports, then the devices would each have their own specific methods for resetting them to any particular state.
