(0, 1): Use this setting if echoes on the line are
interfering with the set-up protocol at the start of
transmission. The machine will then wait for the
second DIS or NSF before sending DCS or
NSS.
Do not change the settings.
This bit determines the capabilities that are
informed to the other terminal during
transmission.
For example, if ECM is switched on but is not
wanted when sending to a particular terminal,
use the (0, 0) setting.
(BR1: Do not change the settings.)

COMMENTS
If training with a particular remote
terminal always takes too long, the
initial modem rate may be too high.
Reduce the initial Tx modem rate
using these bits.
Note: 12,000 and 14,400 bps speeds
are not available with this machine.
Do not change the settings.
