No!

Failure to transmit a break is very likely to be the modem's fault.
Synchronous modems (e.g. 212) usually receive characters asynchronously
from the terminal/computer with one UART (or moral equivalent) and
synchronously reserialize them with another.  So if the logic inbetween
suffers brain damage (usually inherited from its designer) a break condition
may not even be detected, much less propagated.

Since the modem in question is theoretically "intelligent", it is clear that
somewhere in modem-land there is a brain-damaged programmer who must bear
the responsibility for the canard.
