Curiox Laminar Wash HT2000 system.

A benchtop Laminar Wash station for Curiox DropArray plates. Commands are ASCII payloads wrapped in a fixed binary frame; replies are fixed-length and carry a status digit (0 ready, 1 busy, 2 error, 3 stopped).

Serial settings:

115200 baud, 8 data bits, no parity, 1 stop bit, no handshake.

Frame layout of a command:

FF FF FF FF FF 01 | <len> | <payload ASCII> | <checksum hi> <checksum lo> | FF

where <len> is the payload length and the checksum is the low 16 bits of (sum of payload bytes + length), sent high byte first.

Commands:

0            ping / status (15-byte reply)
4            enquire report (42-byte reply)
201          recover home
202          switch from service to operation mode
210          standard wash
211          toggle tray
221/222/223/224  prime: standard / head / pump / short
231          drain aspirator
232          drain spill tray

Every action other than ping and enquire-report returns an 11-byte acknowledgement.

Not verified: has NOT been tested against hardware in PyLabRobot. A warning is emitted at setup.
