DW Host is designed to operate under DOS 3.0, and up, on IBM PC's,
XT's, AT's and compatibles equipped with Hayes 1200-compatible modems.
If DW Host has been configured to answer on true ring detect, the
modem cable used must have pin 22 (ring indicate) connected. Also pin
20 (Data Transmitter Ready signal) must be connected and the modem
must be capable of providing result messages indicating baud rate at
connect time (e.g., CONNECT 1200). Recommended Hayes switch settings
are:
SW 1 - Up, DTR normal (pin 20 controlled by program)
SW 2 - Up, Verbal result messages sent (not numeric result codes)
SW 3 - Dn, Result messages sent (not quiet mode)
SW 4 - Dn, Commands not echoed back
SW 5 - Dn, Auto Answer suppressed (controlled by program)
SW 6 - Up, Carrier detect indicated by modem (not always on)
SW 7 - Up, Single phone line connection
SW 8 - Dn, Normal "AT" command set enabled
If you are using a modem other than the Hayes standard, make sure that
its basic configurable functions are set up the same as above. If
your modem does not have switches for one or more of the above
functions, there should be appropriate AT commands to achieve the same
state. Please consult your modem owner's manual.
DW Host has been improved so that the complication of having
controlling batch files is no longer a requirement. There may be
circumstances, however, that may require you to use a batch file (like
HOST.BAT, included in the distribution archive), but more on that
later. To install the software you need only copy DWHost.COM,
DWHost .OVR, and CONFIG.HLP to a directory from which it will be run.
The directory you choose should be the default directory when DW Host
is invoked. This will already be done if you run the INSTALL program.
To configure DW Host, run it for the first time in LOCAL mode so that
it won't look for your modem and attempt to initialize it. Enter the
command: DWHost L . The L command line parameter specifies LOCAL
mode. Initially, the file DWCONFIG cannot be found, you are so
informed, and the configuration/setup screen is presented with default
settings. If you take some time with this screen and use the F1 key
to display the available help for each configuration item, you'll have
a good understanding of DW Host capabilities when you finish. Hit the
F10 key to save the configuration information. After DW Host returns
to its status screen, hit F1 or F2 to quit operations in LOCAL mode.
If all necessary configuration information has been specified and
you've set up whatever batch files and/or other programs that are to
be accessed from remote through DW Host, your're ready to try bringing
up DW Host for its first test run. The command DWHost with no
command line parameters should be tried next. If the code displays a
status screen and "Waiting for a call" in the status field, you're
ready to try calling in.
As indicated on the screen, you may exit DW Host by pressing F1 or F2
(choose F1 if you wish to have the line ring BUSY to anyone calling).
DWCONFIG is a straight ASCII file and can be modified using any ASCII
editor so long as its lines are not interchanged and the limits of the
variables (as specified by the original prompts for the data) are not
exceeded. It may be necessary to modify this file from remote, in
which case the DOS EDLIN, or your favorite line editor may be used.
