                                  INTERLNK

Connects two computers via parallel or serial ports and enables the
computers to share disks and printer ports. For example, you could connect a
laptop computer to a desktop computer and share files. You must install the
<INTERLNK.EXE> device driver before you can use this command.

Syntax

    INTERLNK [client[:]=[server][:]]

To display the current status of the Interlnk program, use the following
syntax:

    INTERLNK

Parameters

client
    Specifies the letter of the client drive that is redirected to a drive
    on the Interlnk server. The drive must be one that was redirected when
    you started Interlnk.

server
    Specifies the letter of the drive on the Interlnk server that will be
    redirected. The drive must be one listed in the This Computer (Server)
    column of the Interlnk server screen. If no drive letter is specified,
    the client drive will no longer be redirected.

Related Commands

For more information about the Interlnk device driver, see <INTERLNK.EXE>.

For more information about Intersvr, see the <INTERSVR> command.

For more information about setting the number of available drive letters,
see the <LASTDRIVE> command.

Installing the INTERLNK.EXE device driver

You must use the DEVICE command to install the <INTERLNK.EXE> device driver
before you can use the INTERLNK command.

Canceling redirection on a drive

To cancel redirection of a client drive to a server drive, specify only the
client drive and the equal sign (=).

Starting INTERLNK without a server

If you use INTERLNK to connect to a computer that is not running
<INTERSVR>, INTERLNK will show the connection as three additional floppy
disk drives. However, if you try to show the contents of these drives, they
will appear empty. To show the contents of the redirected drives, the server
must be running INTERSVR.

Assigning drive letters

When you connect two computers using INTERLNK, each additional drive will be
assigned the next available drive letter. Because the <LASTDRIVE> setting in
your CONFIG.SYS file determines how many drive letters are available, make
sure LASTDRIVE is set high enough to accomodate the redirected drives.

Pin Connections for a Serial Cable

This section describes the wiring specifications for serial Interlnk
cables.

Make a serial cable with either a 9-pin or a 25-pin female connector on both
ends. Three wires are required for data transmission: Ground-Ground,
Transmit-Receive, and Receive- Transmit. Seven wires are required if you
want to use the remote copy feature. Wire the cable as follows:

9 pin           25 pin              25 pin          9 pin
=====           ======              ======          =====
pin 5           pin 7   <------>    pin 7           pin 5
(Ground-Ground)
pin 3           pin 2   <------>    pin 3           pin 2
(Transmit-Receive)
pin 7           pin 4   <------>    pin 5           pin 8
(RTS - CTS)
pin 6           pin 6   <------>    pin 20          pin 4
(DSR - DTR)
pin 2           pin 3   <------>    pin 2           pin 3
(Receive-Transmit)
pin 8           pin 5   <------>    pin 4           pin 7
(CTS - RTS)
pin 4           pin 20  <------>    pin 6           pin 6
(DTR - DSR)

Pin Connections for a Parallel Cable

This section describes the wiring specifications for parallel Interlnk
cables.

Make a parallel cable with male DB-25 connectors at both ends. Eleven wires
are required for data transmission.

25 pin          25 pin
======          ======
pin 2   <---->  pin 15
pin 3   <---->  pin 13
pin 4   <---->  pin 12
pin 5   <---->  pin 10
pin 6   <---->  pin 11
pin 15  <---->  pin 2
pin 13  <---->  pin 3
pin 12  <---->  pin 4
pin 10  <---->  pin 5
pin 11  <---->  pin 6
pin 25  <---->  pin 25 (Ground-Ground)

Examples

Suppose drive E exists on a server, and INTERSVR is running. To redirect
drive G on the client to drive E on the server, type the following command:

    interlnk g=e

To cancel the redirection of client drive F, type the following command:

    interlnk f=
