COURIER HIGH SPEED MODEMS
%C1  | Restore configuration. Use this command to | 
  | cancel any configuration changes made during  | 
  | remote access, and restore the original  | 
  | configuration. However, commands that have  | 
  | been written to NVRAM (with &W) will not be  | 
  | restored to their previous settings. Additionally, if  | 
  | you have forced immediate configuration changes  | 
  | (with %C2), those changes cannot be reversed with  | 
  | %C1.  | 
%C2  | Execute configuration. Use this command to force  | 
  | configuration changes to take effect immediately,  | 
  | during the current connection. We recommend  | 
  | against forcing immediate configuration changes  | 
  | unless absolutely necessary, as this can result in an  | 
  | unreliable connection or even a loss of connection.  | 
%Fn Configure data format.
%F0  | No parity, 8 data bits.  | 
%F1  | Mark parity, 7 data bits.  | 
%F2  | Odd parity, 7 data bits.  | 
%F3  | Even parity, 7 data bits.  |
