/* special options per meter
1:
special binary SML option for meters that use a bit in the status register to sign import or export like ED300L, AS2020 or DTZ541
a. obis code that holds the direction bit,
b. Flag identifier,
c. direction bit,
d. second Flag identifier (some meters use 2 different flags),
e. second bit,
f. obis code of value to be inverted on direction bit.
e.g. 1,=so1,00010800,65,11,65,11,00100700 for DTZ541
2:
flags, currently only bit 0 and 1
if 1 fix DWS74 bug
if 2 use asci obis line compare instead a pattern compare
e.g. 1,=so2,2 set obis line mode on meter 1
3:
serial buffers
a. serial buffer size
b. serial irq buffer size, a must be given
c. dumplog buffer size, default is 128 , a and b must be given
e.g. 1,=so3,256,256 set serial buffers on meter 1
4:
decrytion key, 16 bytes hex btw 32 chars without spaces or commas
defining key switches decryption mode on
5:
authentication key, 16 bytes hex btw 32 chars without spaces or commas
needs USE_SML_AUTHKEY
6:
synchronisation timout in milliseconds, after no serial data within this
time serial pointer is reset to zero
7:
on esp32 the uart index may be set, normally it is allocated from 2 down to 0 automatically
thus you can combine serial SML with serial script , berry or serial drivers.
8:
on esp32 1 filter mask
on esp8266 2 filter masks
9:
on esp32 1 filter
on esp8266 6 filters
A:
decryption flags (8 bits)
