%U
n Clear Serial Port Speed
%U0
When issued, allows the current serial port speed (19200 bps or lower) to change to
another speed.
%U1
Always keeps the current serial port speed. To change the serial port speed, you must
enter %U1 each time you change the serial port speed.
%U2
Allows the current serial port speed to change from any speed.
NOTES
•
You do not need to issue %U when bps rate adjust causes the serial port speed to
change during a connection.
•
You need to issue AT%U0 when changing from 11-bit characters to 10-bit
characters, and from 10-bit to 11-bit.
•
When the serial port speed is set to 38400 bps or higher, it cannot be changed until
you enter an AT%U command or reset the modem.
*U Update Remote Access Configuration
Saves configuration changes made during a Level 1 remote access session. At
disconnect, the modem loses configuration changes you made during a Level 1 session
if you do not enter *U, and it restores the original configuration. This command does
not affect remote access configuration commands. Stored telephone number changes
take effect immediately during a remote access session.
NOTE
To save the configuration even after the modem is reset, also issue either &W or
*W.
