the status message is retrieved from the AMIS- -49587 by a
hardware event only. To get the status message the serial
driver on the external CPU needs to pull the T_REQ HW pin
low, like described in paragraph Serial Communication
Interface Physical Layer Description.

get a new status message from the MODEM. Only when the
status message indicates that the buffer is not busy, the
command may be send. The AMIS49587 is the master on
the serial interface and needs to be queried to get access to
the bus.
