21. Release Notes
As of ver 2.23 04/03/2011
Firmware fixes and features:
21.1. Known problems
 The UART does not support odd or even parity, only no parity is supported.
 Flow control: RTS may fail to de-assert quickly enough for some high speed CPUs to
 The RTC on the RN-171 does not keep track reliably. This issue is being investigated and will
