1. At the beginning of transmission of the training pattern for the selected
modulation.
2. If the Final Frame bit is 0.
OK Reported for either of two conditions:
1. If the Final Frame Bit is 1.
2. if the DTE sends only <DLE><ETX> (a null frame) while transmitting flags.
ERROR Reported if five seconds elapse from the time when the modem
reported the CONNECT result code without any additional data transmitted
from the DTE; the modem then turns off carrier and returns to the command
mode.
