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 mode.

n = 0, 1, 8

n = 0* Data mode

n = 1 Class 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 flow 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.
