5 Asynchronous Operating Commands Table 10: Command Operation \R Causes ring indicate signal on pin 22 to turn on (high) during each ring and remain on during the call \R1 Causes ring indicate signal on pin 22 to turn on (high) during each ring and turn off (low) when the call is an- swered* *default Request to Send / Clear to Send &R When the modem is operating in nonbuffered mode (direct mode) or in synchronous mode, AT&R enables the RTS to CTS delay determined by the value in S26. AT&R1 forces CTS high and the modem ignores RTS (default). With AT&R2 selected CTS goes high when carrier is detected. AT&R9 forces CTS to follow the state of RTS without delay. Table 11: Command Operation &R Enables RTS to CTS delay &R1 CTS forced on* &R2 CTS follows DCD &R9 CTS equals RTS *default Note: RTS/CTS delay is not valid in buffered mode or with error control enabled.
