Command Echo
E0 Inhibits the echoing of commands to the local device.
E1 Echoes commands to the local device.
%E
n
Auto-Retrain
%E0 Disables the automatic retrain sequence.
%E1 Enables the automatic retrain sequence (at 2400 bps or higher).
When %E1 is set and line quality is too poor to sustain
communications, the modem tries up to three times to
resynchronize the modems (for a total of up to six seconds) before
hanging up. The modem can retrain during connections at 2,400
bps or higher. Use ATO1 to force the retrain sequence when %E0
is set.
-E
n
Modem-Port Data Length
-E0 Enables 10-bit data during normal mode connections.
-E1 Enables 11-bit data during normal mode connections.
Determines the number of data bits used on the modem port
during normal mode connections (when \N0 is set) when the serial
port is configured for asynchronous transmission of 11-bit
characters. Both modems must be set to the same number of data
bits.
20DCD On (Off for a few seconds at disconnect only), DSR On,
CTS On
2 1 DCD, DSR, and CTS On (Off for a few seconds at disconnect)
2 2 DCD, DSR, and CTS On (Off for a few seconds at disconnect)
2 3 DCD Off at disconnect then On, DSR complies with the ITU-T
recommendations, CTS On
24DCD On (Off for a few seconds at disconnect), CTS/DSR comply
with the ITU-T recommendations
NOTE The modem ignores %E0 during V.34, V.FC, V.32bis, and V.32
connections.
