length of all the values assigned to
COMPRESSION_STRING
cannot exceed
115 characters.
DIAL_METHOD:
This keyword specifies how the modem attempts to dial
phone numbers. This can be
T
for tone dial or
P
for pulse dial.
ECHO:
This keyword indicates whether responses received from the modem
should be displayed to the screen. Enable the keyword by setting the value
string to
T
(for true); clear it by setting the value string to
F
(for false).
FAIL_STRINGS:
This keyword is a list of response strings (expected responses
from the modem) that indicate that the connection to the remote end failed.
These strings contain text (such as
NO
CARRIER
and
BUSY
) that the modem
might return on an error. Using a configurable list of errors allows the serial-in/
out modem run-time library to compensate for differences in messages between
individual modems. Use the
FAIL_STRING
keyword as many times as
necessary to create the desired list. However, the combined length of all the
values assigned to
FAIL_STRING
cannot exceed 115 characters.
HANDSHAKING:
This keyword controls the type of handshaking the Falcon
will perform with the modem. Generally, RTS/ CTS handshaking is necessary
to support the advanced functions of modems, such as compression and error-
correcting protocols.
Set this keyword to
N
for no handshaking,
X
for Xon/Xoff software flow
control, or
R
for RTS/CTS hardware handshaking.
INIT_STRING:
This keyword specifies the string to use to initialize the
modem. The initialization-string value should begin with the AT sequence for
Hayes-compatible modems, as the serial in/out modem routines do not attach
these characters to the beginning of the initialization string before sending it to
the modem.
LOCKED_BAUDRATE:
When enabled, this keyword indicates that the local
modem is configured to communicate with the PC at a fixed baud rate,
regardless of the speed of the connection between the modem and the remote
The
HANDSHAKING
keyword in the modem-initialization file takes precedence over
any flow-control options selected on the command line in XFER.
