&R
When the modem is operating in nonbuffered mode
(direct mode) or in synchronous mode, AT&R en-
ables 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.
*default
Note: RTS/CTS delay is not valid in buffered mode
or with error control enabled.
