Matching the Port and Device Characteristics

CHARACTER SIZE and PARITY Settings

The AUTOBAUD characteristic functions only if the input and output speeds of the port device are the same and the character size and parity settings have the combinations listed in the following table:

Character Size

Parity

 

 

8

None

7

Even

 

 

Example: Disabling AUTOBAUD

The following example shows how to disable the autobaud characteristic:

Local> CHANGE PORT 5 AUTOBAUD DISABLED

CHARACTER SIZE

The CHARACTER SIZE characteristic indicates the number of bits in a data character. The access server supports character sizes of 7 or 8 bits, and the default is 8 bits.

Refer to the operator’s guide for the port device to determine appropriate character size.

If you enable autobaud, the access server automatically adjusts the character size.

Example: Setting the CHARACTER SIZE

The following example shows how to set the character size:

Local> CHANGE PORT 5 CHARACTER SIZE 7

PARITY

The PARITY characteristic determines the type of parity checks that the access server performs. If you enable autobaud, the access server automatically adjusts the parity.

PARITY Settings

The following table lists the available parity checks:

Setting

Check Performed Per Character

 

 

Even

Even number of one bits

Odd

Odd number of one bits

Mark

A set parity bit
