I am trying to send TTL signals to Acqknowledge via serial port. I am using The Black Box ToolKit USB TTL Module v1.

When I send signals using the proprietary Black Box software Acqknowledge receives them immediately and as expected. When using the serial port monitor in Inquisit however, the sending is inconsistent, sometimes requiring me to click 'send' twice or more in order to actually send the signal, but most of the time it doesn't work at all. It consistently isn't working via the script.

Also interesting to note, when Inquisit does send the signal, it does not align with the expected lines i.e. sending '00000001' should turn on line 1 (which it does via the Black Box ToolKit Interface), but instead it turns on lines 1, 3, and 4.
The expected binary to elicit this behavior is '00001101'

Additionally, sending '00000100' works much more consistently in Inquisit, but again requires clicking send at least twice (but sometimes more) and turns on lines that aren't expected. This should turn on line 3 only, but instead turns on lines 1, 3, 4, 5, 7, and 8. The expected binary to produce this behavior is '11011101'

The inconsistent behavior is the most confusing part of this to me, as I can't create a heuristic in order to troubleshoot. I am hoping the information I provided will ring a bell for someone who has used USB serial port hardware before. I am happy to provide some more information as needed, but this is a comprehensive description of what I have been experiencing.

Thanks!
