CompareBits - Specify number of bits that must match EOS character to complete read operation, or to assert EOI line

Description

You can configure CompareBits to be 7 or 8. If CompareBits is 7, the read operation completes when a byte that matches the low seven bits of the End-Of-String (EOS) character is received. The End Or Identify (EOI) line is asserted when a byte that matches the low seven bits of the EOS character is written. If CompareBits is 8, the read operation completes when a byte that matches all eight bits of the EOS character is received. The EOI line is asserted when a byte that matches all eight bits of the EOS character is written.

You can specify the EOS character with the EOSCharCode property. You can specify when the EOS character is used (read operation, write operation, or both) with the EOSMode property.
