failure-string
String that is sent to the serial device when a connection fails. If no string is entered,
then the string NO CARRIER will be sent.
host
The target host name.
init-string
You can specify additional vmodem commands that will affect how vmodem starts. The
following commands are supported: ATQn, ATVn, ATEn, ATS0, AT&Z1, AT&Sn,
AT&Rn, AT&Cn, AT&F, ATS2, ATS12, and ATDS1.
See VModem Initialisation Commands in the IOLAN User’s Guide for a more detailed
explanation of the support initialisation commands.
mode
Auto mode establishes the connection when the line becomes active. You must supply
the AT command or phone number that will start the connection; see
Set
Vmodem-Phone on page 89 for the command parameters to set the AT command or
phone number.
port
The port number the target host is listening on for messages.
response-delay
The amount of time, in milliseconds, before an AT response is sent to the requesting
device. The default is 250 ms.
signals dcd
Controls the state of the DCD signal.
z always-high = DCD signal will always stay high.
z follow-connection = DCD signal will be high when an end to end connection is
established and low when it is not.
Since the IOLAN does not have a physical DCD pin, you need to re-map the DTR or
RTS signal to DCD to have the signal present. (see next option).
signals dtr
You can specify how the DTR signal pin acts during your modem application
connection, as itself (DTR), as DCD, or as RI.
signals rts
You can specify how the RTS signal pin acts during your modem application
connection, as itself (RTS), as DCD, or as RI.
