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:
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:
Character Size Parity
8 None
7 Even
Setting Check Performed Per Character
Even Even number of one bits
Odd Odd number of one bits
