E22 UART fixed point transmission

Hello I am using both E22-900T22DC and E22-900T30DC. For testing I am using direct communication from a PC terminal, rather than arduino. I can make everything work fine, except "Fixed Point Transmission". I see the E22 library supports this and I have carefully examined what the library is doing. When bit 6 of register 0x6 is set high, I do not receive data. I have scoped the UART data going to the module, and it includes the correct address and channel data in the first three bytes, as expected. The receiving module is also configured exactly as in the E22 library example. When the Fixed Point Transmission bit is low, addressing works as expected (data sent when RX and TX modules have same address and channel, and also FFFF broadcast and FFFF monitor works for channels). Otherwise I am wondering if the firmware in my modules has a bug. Thanks for any comments! Ben
