• No baud rate setting for the PIL-Box any more.
• Improved PIL-Box transfer speed at 115200 baud when PIL-Box working in device mode.
• Added 230400 baud support for next PIL-Box generation with firmware 2.1.
  

As mentioned by Christoph, ILPer 2.2 supports a faster communication speed at 230 kbps. If you recently bought a PIL-Box with firmware 2.1 (from sn P229-2016), all you have to do is to remove the internal jumper on JP2 inside the PIL-Box and will enjoy the improved speed.
For users of PIL-Box with firmware 1.x, it is possible to upgrade to 2.1 by changing the microcontroller. No modification of the board is needed. The performance gain vs firmware 1.5 is about 40% (°), depending on your PC hardware and OS. Contact me for more details.

Edit: (°) performance gain with the HP-71B. No significant gain with a HP-41C since it is sooo slow...
