Commands to set the modem's flow control.
Use a single command string. For example,
(1)
HKR, Settings, FlowControl_Off,, "&K0"
HKR, Settings, FlowControl_Hard,, "&K3"
HKR, Settings, FlowControl_Soft,, "&K4"
(2)
HKR, Settings, FlowControl_Off,, "\Q0"
HKR, Settings, FlowControl_Hard,, "\Q3"

If the modem does not support any or all of the FlowControl settings, the corresponding registry entry should not be included. The supported commands must be indicated in the ModemOptions member of the Properties registry entry for the FlowControl settings to be used.
