Command
1. When in autobaud mode, \B0, \B1, and \P1 will not be detected automatically. The combination of \B2 and \P3 will be
2. The autobaud feature does not detect this rate.
3. Default is \T9 if a pulldown resistor is connected to the autobaud strap pin; otherwise, the default is \T16.

detected. This is compatible with seven data bits, no parity, two stop bits. Seven data bits, no parity, one stop bit may be
forced by sending AT\T17\B1.

Use RTS/CTS
Use XON/XOFF flow control for modem-to-DTE interface. Does not enable modem-to-modem flow
control.
DTE rate—Change DTE rate. When the Si2493 is configured in autobaud mode (default), \T0
through \T15 will lock the new baud rate and disable autobaud. When the ISOmodem
autobaud mode (the autobaud strap pin low on powerup), the result code “OK” is sent at the old DTE
rate. Subsequent commands must be sent at the new rate.
