I/O Port #H
The module has 16 I / O port lines, which can be expanded to up to 125. If the port input pins are changed, macros can be started, see #MHP, and #MHB.

#HPC |
Port, I/O, I/O [Port+1], ... |
The command defines the direction (I/O) of the individual port pins bit by bit for an entire Port [0 ... 15]:

#HPR |
Port (0), Number(2) |
The command puts the state of one or more (Number) of ports (starting with Port) in the send buffer. The feedback is structured as follows:

The port expander with address 0 is internally available, that means without external hardware the return value is 1.
