Subject: Modem Status

Hello all,

I am trying out the libftdi for the first time.

After a hardware reset of the FT232BL, I poll the modem status and I get this value 0x7001 (unsigned short). The file ftdi.c says that the first four bits of the first byte must be 0.

"  Layout of the first byte:
    - B0..B3 - must be 0"

What does this mean when bit 0 is set at 1 instead of 0?

Thank you.

Pierre
