Running on a TS-7200 but that doesn't really matter. What's amusing is that
running a DOS program on a computer with a serial interface configured for
9600:O81 I can send message frames to the TS-7200 serial interface /dev/ttyAM0
which is configured as 9600:N81 and despite the parity mismatch, the CRC
appended to my inbound frame matches the TS-7200's computed CRC.
The only thing I can think of is that when performing parity bit stuffing on
one end and no bit elimination on the other, while the data in the received
frame on the TS-7200 is wrong, the CRC match because the CRC is also bit
shifted -- except that the CRC is a recursive polynomial so I would not have
expected it to match.
Kind of strange that a parity mismatch passes CRC checks some how.
Unless I need coffee and missed something. }:-}
