Configure Flow Control
To configure your modem, refer to the modem’s documentation. To configure flow control on the
SCS, use the
Set/Define Ports Flow Control
command. Figure 8-49 displays an example.

Configuring RTS/CTS Flow Control
Note:
For this command’s complete syntax, see Set/Define Ports Flow Control on page
12-72.
8.12 Serial Signals
Two of the modem signals (DSR and DCD) can be used to control when the SCS ports are active. By
monitoring when these signals are asserted or deasserted (dropped), SCS ports can be logged out or kept
from starting. The SCS uses DTR to control attached devices.
All of the SCS’s DB25 and RJ45 signals are displayed in the following figures.
