2.1.35 Receive Timeout
0 to 65535
milliseconds
This parameter specifies the minimum number of milliseconds to wait after the
first byte of a frame is received before a timeout condition is set. Be careful not to
set this parameter too small. If the timeout condition is set, all bytes in the frame
received will be discarded.
2.1.36 Hardware Handshaking
N
ONE
,
RTS/CTS,
DTR/DSR, M
ODEM
Selects the hardware handshaking type.
RTS/CTS, DTR/DSR and M
ODEM
options are most commonly used for older telephone line modems.
RTS/CTS
and
DTR/DSR are also commonly used with leased-line data modems. The
M
ODEM
option is also commonly used with dial-up modems. When the messages
must go out if the modem is not connected, the gateway will assert the DTR line
which will cause the modem to dial the number in the modem’s configuration.
The gateway does not have the functionality to dial the number to be called for
the modem. The gateway reconnects after 30 seconds of inactivity.
