will read high (they have internal pullups).

<090> b l Read single input line

<090> b l..l Read multiple input lines

Parameters:

- 090 is the default command name.

- B is the I/O board number (1..2)

- L is the input line number (1..8)

Notes:

To provide customized messages for the input lines, see Command 091.

091: Execute Input Line High or Low Macro

This command is similar to Command 090. The difference is that instead of speaking the word

"high" or "low", the high or low internal macro for that input line will be executed. This allows you

to program custom messages such as "door open" and "door shut". See Chapter 8 for to find the

macro numbers for each input line.

<091> b l Execute input line macro for 1 input line

<091> b l..l Execute input line macros for multipleinput lines

Parameters:

- 091 is the default command name.

- B is the I/O board number (1..2)

- L is the input line number (1..8)

Notes:

Multiple input lines can be read with one call to this command by entering more than one

port number here.
