Flow Control: Technical Notes

http://www.racal.com/dcom/modem.tutorial.html

For modems (and modem cables, if you have an external modem) which properly support flow control, Hardware flow control can reduce the chance of a communication error.

For more information about Time Division/Hardware flow control, see this document on the MFM web:

You should first select Hardware flow control. If you have any problems with flow control, you'll probably notice them first while you are viewing photos. If you experience communication errors, photo lockup, smeared photos, diagonal stripes (sun rays), or no color data, you should try Time Division/Hardware flow control as well as making sure you selected the correct modem.
