Great to hear!! ;D  I've been on the road since the latest FW release, so I haven't had a chance to test it at all.

Teneyes:
Here I am checking  the recording & decoding of 2 Channels RS232
      230byte bursts at 10sec on Ch1,   Ch2 continuous
Note:  The decoding of a new frame in playback takes about 2 seconds at this setup     

Teneyes:
Data Decoding Limit  ( RS232 test)

it appears that to Decode without  Errors, at least 28 Pts must be allocated for Each 'BIT' of data or else the Decode will miss a byte.

To test I used:
            2ms/div
            70Kpts/display
            89.2Kb.s   all OK   = 28.027 Pts/bit
            89.4Kb/s   Errors occuring
See Pics

Teneyes:
EDIT:    Max=900k in Latest Firmware 00.03.00.01.03
A High Speed Test of  RS232 Data Recording & decoding
 I used:
          892Kb/s      (maximum trigger setting is 900000)
          140Kpts/display
          475 Byte Block
          396 us/div
          3.96 us/div  Zoom

          Recorded 508  Frames

  For a Total of  241300  Bytes recorded
