For noninteractive communications devices, PCs and computers, enable the
SIGNAL CONTROL and DTRWAIT features on the communications server.
You can enable DTRWAIT only if you enable SIGNAL CONTROL. To enable
SIGNAL CONTROL and DTRWAIT, perform the following:
Local> DEFINE PORT
port_number SIGNAL CONTROL ENABLED
Local> CHANGE PORT
port_number DTRWAIT ENABLED
You can also set the flow control for the port. You can set flow control to
XON/XOFF, DSR, or DISABLE. Flow control is XON/XOFF by default. This is
usually the appropriate setting for printers, although you can perform printer
flow control using DSR. Refer to Ethernet Communications Server Management
for details. Note that if you use DSR for flow control, you cannot use DSR for
other features such as automatic port logout.
For PCs and computers configured as noninteractive devices, DSR provides
additional desirable features such as automatic port logout, inactivity logout, etc.
These features, however, cannot be used if you use DSR for flow control instead of
XON/XOFF. It is recommended that you configure ports to which you connect PCs
or computers with XON/XOFF flow control. Refer to Ethernet Communications
Server Management for details on flow control.
To set XON/XOFF flow control for an interactive device, perform the following:
Local> CHANGE PORT
port_number FLOW CONTROL XON
For additional information and examples on configuring interactive devices for
LAT sessions, refer to Ethernet Communications Server Management.
For additional information and examples on configuring interactive devices for
Telnet sessions, refer to "Configuring and Managing Telnet Services" in Ethernet
Communications Server Management.
