HCU Usage
The command line arguments for HCU are:
HCU [options] [string1 . . string(n)] 1 [@filename]
The optional [options] arguments may include:
-C or -Ii
-Ddevname
-Ppassword
-Tnnn
-Bbps
-N
-x
To indicate to HCU that this is a Connection operation (the
default), or a Hangup operation. For example, a host
application that needs to communicate with a remote SLTA-10
Adapter can be invoked from a DOS batch file, with preceding
and subsequent calls to HCU. Prior to invoking the application,
HCU is called to connect to the remote SLTA-10 Adapter.
Following execution of the host application, HCU is called to
disconnect from the remote SLTA-10 Adapter.
To select a non-default device name, where devname is the
device name, default LONI .
To indicate a password, where password is a string of up to 6
characters, which will be sent downlink to the remote SLTA-10
Adapter once the connection is made. Each character in the
password string may be any eight bit value. Non printable
characters may be represented by hex or octal values in the
same format as for C strings, such as “\xlO”, or “\020”.
To select a non-default connection wait time of nnn seconds; the
default is 60 seconds. This value limits the period for which
HCU will wait for a connection to be completed.
To change the LDVSLTA network driver serial bit rate. The
default is the current setting of the network driver. This
controls the link rate between the host computer and the
modem. The acceptable values for the bps value are the same
as those available on the SLTA-10 Adapter: 12 0 0, 2 4 0 0, 9 6 0 0,
14400,19200,38400,57600, and 115200.
To enable the buffered link protocol and disable the
ALERT/ACK link protocol. This option is not recommended for
connection operations.
To exit HCU with the network driver’s modem support mode
disabled. Use with the -H option to disconnect from a remote
SLTA-10 Adapter for subsequent connection to a local SLTA-10
Adapter.
All options must precede string arguments on the command line when
evaluated from left to right.
The string arguments are modem command strings, typically Hayes-compatible
AT commands. These strings are sent directly to the modem. For details of the
allowable commands, see the documentation supplied by your modem
manufacturer. If more than one string is included, HCU will wait for the OK
