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 Si2457/34/15/04 is configured in autobaud mode (default),
\T0 through \T15 will lock the new baud rate and disable autobaud. On the 24-pin version, the ISO-
modem® is not in autobaud mode (pin 18 low on powerup), the result code “OK” is sent at the old
DTE rate. Subsequent commands must be sent at the new rate.

Autobaud on
Autobaud off; lock at current baud rate.
Serial mode—causes a low pulse (25 ms) on RI and DCD. INT to be the inverse of ESC. RTS to be
inverse of CTS.
Parallel mode—causes a low pulse (25 ms) on INT.
This command terminates with a RESET.
