(NVRAM) using &W. (If the profile is not written, it is assumed that the device
does not wish the session profile to be preserved between ATLAS system
restarts.)
If a new call is made and a different modem allocated, the new modem is initial-
ized with the port’s current profile. When a change is made to a field in the termi-
nal menu, the new value updates both the stored and current profile. (See
Appendix B, AT Commands.)
Port Name
Write security: 3; Read security: 5
Any alphanumeric name up to 16 characters can be entered to uniquely identify
each port on the Async-232 Module.
DTE Bit Rate
Write security: 3; Read security: 5
Selects the bit rate used at the connector between the Async-232 Module port and
the DTE. Changing this field hangs up a connected call and requires confirma-
tion. Selectable values range from 300 to 115.2 Kbps. Higher bit rates normally
require hardware flow control.
The selected bit rate must match the speed configured on the DTE. The Async-
232 Module does not support Autobaud.
Flow Ctr (Flow Control)
Write security: 3; Read security: 5
Selects the port flow control method. The chosen method must match the method
used by the DTE device attached to the port. Changing this field hangs up a con-
nected call and requires confirmation. Flow control methods include Hardware,
Software, and None.
Hardware
Hardware flow control monitors RTS from the DTE and controls CTS to indi-
cate flow control status. Hardware flow control should be used in all cases
except when it is not supported by the attached DTE.
Software
Software flow control uses XON and XOFF characters in the data stream to
control flow.
None
No flow control selected for this port.
Call Dir (Call Direction)
Write security: 3; Read security: 5
Call Direction options include In Only, Out Only, and In & Out.
In Only
Connected DTE only answers incoming calls through this port.
Out Only
Connected DTE only initiates outgoing calls through this port.
