Flow Control
Select Flow Control Method
0, 1, 2, 3-255
OK or ERROR
The +FLO? command lets you select the method of flow control provided and used by the
modem. If +FLO=0, some other method (such as credit flow control) is used. The Xon-Xoff
method is required. Xon is the ASCII character <DC1> (11 hex). Xoff is the ASCII
character >DC3> (13 hex). CCITT V.24 circuits 106 and 133 are optional flow control
methods. If circuits 106 and 133 are not used (+FLO<>2), then circuit 106 is held On
whenever +FCLASS=8.
In Voice mode, circuit 105 has no effect on the state of transmitted data. (Circuit 133
normally reverts to use as circuit 105 (RTS) when not used for Flow Control.)

Notes:
Y = will hang up; N = will not hang up
How +VNH is reset:
DTE uses +VNH command to change the setting.
DTE issues another +FCLASS mode change without issuing another +VNH.
A hang-up event occurs (see this table).
DTE issues +VIP command.

Reports current or selected values.
Reports supported range of parameter values.
Disables Xon-Xoff and 133/105 flow control
Enables Xon-Xoff flow control in either direction
Enables CCITT Circuit 133 for flow control of the modem by the PC; use
CCITT Circuit 106 for flow control of the PC by the modem.
Reserved for future standards.
Modem enables automatic hang ups as is normal in other modes.
Modem disables automatic hang ups usually found in the other non-
voice modes.
The modem disables automatic hang ups in the other non-voice modes.
The modem performs a “logical” hang up (returns OK result code).
