\G n Modem-Port Flow Control
\G0 Disables modem-port flow control.
\G1 Sets modem-port flow control to XON/XOFF.
\G2 Sets modem-port flow control to unidirectional XON/XOFF.
Sets the flow control method used to pace data between modems
during a normal mode connection. When \G1 is set, the modem
sends an XOFF character to stop receiving data, and sends an
XON character to resume. When \G2 is set, the modem sends
XON and XOFF characters to the remote device but ignores XON
and XOFF characters from the remote device.
Reliable mode has its own method of flow control and ignores
NOTES
the \G setting, but \Qn settings remain active.
Both modems must have the same primary flow control
characters set during normal connections. (See the :T9 and
:T10 register descriptions.)
H Hang Up
H0 Disconnects from the remote system and hangs up the telephone
line.
H1 Disconnects from the remote system and goes off hook in
command mode.
The modem ignores ring signals and positive transitions of DTR
for 5 seconds after disconnect.
If %D is set to a value other than 0, hang up may not occur
NOTE
immediately.
