Communication Port Options 2, Parity, Stop Bits

3. Configuration Options

Table 3-38. Communication Port Options (2 of 5)

Parity

Possible Settings: None, Even, Odd

Default Setting: None

Provides a method of checking the accuracy of binary numbers for the COM port. A parity bit is added to the data to make the “1” bits of each character add up to either an odd or even number. Each character of transmitted data is approved as error-free if the “1” bits add up to an odd or even number as specified by this configuration option.

None – Provides no parity.

Even – Makes the sum of all 1 bits and its corresponding parity bit always even.

Odd – Makes the sum of all 1 bits and its corresponding parity bit always odd.

Stop Bits

Possible Settings: 1, 2

Default Setting: 1

Determines the number of stop bits used for the COM port.

1 – Provides one stop bit.

2 – Provides two stop bits.

Ignore Control Leads

Possible Settings: Disable, DTR

Default Setting: Disable

Specifies whether DTR is used.

Display Conditions – This option does not apply to the FrameSaver SLV Router.

Disable – Treats control leads as standard operation.

DTR – Ignores DTR. This may be necessary when connecting to some PAD devices.

Login Required

Possible Settings: Enable, Disable

Default Setting: Disable

Determines whether a user ID and password (referred to as the login) is required in order to log on to the asynchronous terminal connected to the COM port.

Display Conditions – This option only appears when Port Use is set to Terminal.

Enable – Requires a login to access the menu-driven user interface.

Disable – Does not requires a login.
