is selected, the eyesite 550 sends to X-ON and X-OFF

characters to control the flow of information over the video

call. Soft Handshaking is needed when the local connection

may be set for a baud rate which is equal to or greater than the

video connection rate, or when the equipment at the local end

may not always be able to keep up with the incoming data

transfer.

transmits this line to the remote location, allowing for a pass

through of the RTS/CTS line used by NetMeeting and any

other program/device that uses these lines for handshaking.

Select

NONE

if no Handshaking is required.
