Modem Cable (Full-Handshake) - Silicon Graphics Origin200 Owner's Manual

Modem Cable (Full-Handshake)

This modem cable provides request-to-send (RTS) and clear-to-send (CTS) connections,
and is appropriate for a modem with RTS/CTS flow control. This cable also works with
other serial devices (except printers and terminals) that do not need RTS/CTS flow
control, and you can use it with a null modem adapter to attach printers and character
terminals. You can purchase this full-handshake serial cable from Silicon Graphics or
from your local service provider.
