All values are 16-bit signed integers using scaled (*100) units.
<temp> is degrees C
<rh> is %
<press> is kPa.

<status> is three unsigned 8-bit values. (See Command A)
<press> is 32-bit unsigned integer using scaled (*10^decimals) units. Units is kPa.
<decimals> is 8-bit signed integer

<versionmajor> is an unsigned 8-bit unsigned value
<versionminor> is an unsigned 8-bit unsigned value
<HWVer> is an unsigned 8-bit unsigned value
<SubModel> is an unsigned 8-bit unsigned value
<model> is a 2-byte flag used to differentiate between software with different command sets.
W - Write EEPROM
Command: <start><addr><Size>W<addr1><data><chk>

<addr1> is a 16-bit address, least significant byte first.
<data> is 8 bytes read from EEPROM.
To write the eeprom, set the high byte of <addr> to 00H.
To write low memory, set the high byte of <addr> to F0H.
To write extended memory, set the high byte of <addr> to F1H.
Address should be an 8-byte boundary.
Z - Zero

<channel> is an 8-bit value.
<channel> selects channel to be calibrated. P for pressure, H for humidity, T for temperature.
<value> is a 16-bit signed integer using scaled (*100) units matching select channel.
<status> is three unsigned 8-bit values. (See Command A)
<counts> is an unsigned 16-bit value.
