Basic Configuration
• SequenceDisconnect: Enables/Disables and configures the Resident Disconnect
command. This offers the option to disable the Sequence Disconnect, select a one
character format or a three character format. (Default = One Character.)
• InactivityTimeout: Enables and selects the Timeout Period for this port. If
enabled, the Serial Port will disconnect when no additional data activity is detected
for the duration of the timeout period. (Default = 5 Minutes.)
• CommandEcho: Enables/Disables command echo. When disabled, commands
sent to the Serial Port will still be invoked, but keystrokes will not be displayed.
(Default = On.)
• AcceptBreak: Determines whether the port will accept breaks received from the
attached device. When enabled, breaks received at the port will be passed. When
disabled, breaks will be refused at this port. (Default = On.)
PortModeParameters:
• PortName: Allows you to assign a name to the Serial Port. (Default = undefined.)
• PortMode: The operation mode for this port. (Default = Normal Mode)
Depending on the Port Mode selected, the AFS-16 will also allow the definition
of additional parameters listed below. In the Text Interface, these parameters are
accessible via a submenu, which will only be active when the appropriate port
mode is selected. In the Web Browser Interface, fields will be "grayed out" unless
the corresponding port mode is selected.
NormalMode:Permits access to command mode. When Normal Mode is
selected, the following mode specific parameter can also be defined:
DTROutput: Determines how DTR will react when the port disconnects. DTR
can be held low, held high, or pulsed for 0.5 seconds and then held high.
(Default = Pulse.)
 ModemMode: Permits access to command mode and simplifies connection
to an external modem. Modem Mode ports can perform all functions available
in Normal Mode, but Modem Mode also allows definition of a Hang-Up String,
Reset String, and Initialization String:
ModemResetString: Redefines the modem reset string. The Reset String
can be sent prior to the Initialization string. (Default = ATZ.)
ModemInitializationString: Defines a string that can initialize a modem to
settings required by your application. (Default = AT&C1&D2S0=1&B1&H1&R2)
ModemHang-UpString: Although the AFS-16 will pulse the DTR line to
hang-up an attached modem, the Hang-Up string is often useful for controlling
modems that do not use the DTR line. (Default = undefined.)
PeriodicResetValue: Determines how often the Reset String will be sent to
the modem at this port. (15 Minutes.)
