%O n V.23 Equalizer Control
%O0 Disables equalizers in V.23 half-duplex mode.
%O1 Enables equalizers in V.23 half-duplex mode.
Determines if equalizers are set in V.23 half-duplex mode. To
avoid transmission errors during V.23 half-duplex connections,
equalizer settings must be the same on both modems.
-O
n
Serial-Port Parity
-O0 7 data bits, odd parity.
-O1 7 data bits, even parity.
-O2 7 data bits, mark parity.
-O3 7 data bits, space parity.
-O4 8 data bits, no parity.
-O5 8 data bits, odd parity.
-O6 8 data bits, even parity.
-O7 8 data bits, mark parity.
Allows you to change the serial-port parity setting that is
automatically set by the AT sequence.
You can also use the -O command to change the serial-port parity
while connected to a remote device. Use this command when the
local device supports XON/XOFF flow control and detects parity.
This command ensures that all XON and XOFF characters
generated by the modem have the correct parity.
You cannot change modem-port parity during a connection.
When parity is required for a connection and is different than the
parity set by the AT sequence, the parity must be set at the same
time the dial command is issued and entered on the same
command line.
For example:
AT-O4D12345 <Enter>
