Functionality
Using the address specified, the Master attempts to estab-
lish a continuous link to the Slave. If a link is established,

are transmitted to the host followed by any
data received from the Slave. When the Master receives a
packet from the Slave with no data, the Master will assume
that the Slave has transmitted all of its data which will
prompt the Master to break the link and send

to its host and increment the Slave address and repeat the
described sequence for the next Slave. When the Slave ad-
dress range is exhausted, the Master will wrap around the
Slave address space and proceed with a new cycle of auto-
poll.

Number of passed bytes in error.
Lowest address of a slave that responded.
Highest address of a slave that responded.
Number of retries.
Number of sync timeouts.
Functionality
Initiate test mode and output results via the serial link. Re-
sults are sent when the maximum amount of information
has been gathered, i.e., before any field of the result buffer
overflows. After the first set of results is sent, the modem
continues test mode normally without spontaneous output.
The very first response from the modem after
k
Ctrl-B
l
is
the command acknowledgment indicating to the host that
the command has been processed and that the modem is
ready to accept new commands. Following the response
are the test results in the format specified below.
The command acknowledgment format is as follows:

identical to Ctrl-B output.
