Function pamoja_serial_port_wait 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_serial_port_wait(
    port: *const PamojaSerialPort,
    micros: u64,
)

Waits, as a protocol does to leave the line silent between frames: the process sleeps on the kernel’s device, and anywhere else the wait is only counted.

Arguments

• port - the port.
• micros - how long.

Safety

port must be a live handle or null.
