For computers and TTYs to communicate with each other, each device must be properly set. Following is a list of setting for various combinations of devices.

NOTE: Voice Carry Over (VCO) and Hearing Carry Over (HCO) cannot be used with ASCII—except when using 2-line versions of these calls.

This information may be specific to Hamilton Relay. Your state relay may have different settings necessary in order to use a computer to connect to the relay.

If you have questions, problems or concerns, please contact Customer Service for the relay in your state—or visit their Web site.
