Table 6-1. Voice Mode Command Descriptions
Note: An asterisk (*) denotes the factory-default setting.
Command Default Description
+FCLASS=8 0
Voice Mode Selection: This command enables or disables voice mode. All voice
mode commands (except for +FCLASS=n) are valid only in voice m ode.
n = 0, 1, 8
n = 0* Data m ode
n = 1 Clas s 1 fax mode
n = 8 Voice mode enabled
+FLO=n 1
Flow Control Select: This command allows the DTE to identify and select the
types of flow control used. DCEs using the IS-101 standard must support in-band
XON/XOFF flow control. XON is the ASCII <DCI> character (11h); XOFF is the
ASCII <DC3> character (13h). The DCE may provide ITU-T’s V.24 CTS (circuit
106) and RTS (circuit 133) for flow control.
n = 0, 1, 2
n = 0 Disables XON/XOFF and CTS/RTS flow control
n = 1* Enables XON/XOFF f low control in either direction
n = 2 The DTE uses ITU-T’s RTS to control flow to the modem; the
modem uses ITU-T CTS to control flow to the DTE.
