REMDISK.EXE
Remote Disk Program
See Also: REMSERV.EXE
REMSERV is usually run on the MX2 (host). REMDISK is usually run on the client (e.g. a
desktop PC).
The remote disk program allows you to access a disk drive on a remote system via a serial cable
and standard PC-style (8250UART) serial port. In a remote disk setup, one system, the one that
shares its drives, is termed the server. The other system, the one that accesses and uses the remote
drives, is called the client. The serial ports on both systems must be connected via a null modem
cable. Remdisk / Remserv works across a standard 3-pin serial cable. The cable does not require
the CTS/RTS DTS/DTR pins.
To use the remote disk, both REMDISK and REMSERV must be running on their respective
systems and must use the same baud rate and packet or nonpacket-style transmission. After
starting both programs, you can access the new drive on the client system. You can change the
default directory to this new drive, copy files to and from the remote drive, and also run utilities
such as CHKDSK on the drive. The remote drive on the server system can be used as any other
drive on the client system.
Syntax
The program REMDISK runs on the client system and creates a new drive letter for the client.
REMDISK uses the next available system drive letter.
For example, if the last assigned drive was D:, REMDISK creates drive E:. This drive acts like
any other drive, except that it requires the serial port. REMDISK.EXE can be loaded by a
DEVICE= command in the CONFIG.SYS or AUTOEXEC.BAT files or it can be entered at the
DOS prompt.
CONFIG.SYS –-- DEVICE=REMDISK.EXE /T15
AUTOEXEC.BAT – REMDISK /B9600 / COM2 /T10
The syntax for REMDISK is:
REMDISK [/U] [/H] [/Bnnnn] [+|-][/Tnnn] [/COMn]
The default is: /B115K+ /COM1 /T3
Option Description
/U Unloads REMDISK from memory, thereby disabling the drive letter and freeing
the memory occupied by REMDISK. This option can only be used when
REMDISK is installed from the DOS command line. A remote disk installed via
CONFIG.SYS cannot be unloaded.
/H Selects hardware handshaking for flow control.
/Bnnnn Selects the baud rate for transmission. Available baud rates are 300, 1200, 2400,
4800, 9600, 19200, 38400, 57600, and 115000. The default baud rate is 115000.
+/- The plus sign (+) specifies packet-style transmission and is recommended for any
baud rate over 19200. The default setting is to include + for packet transmission.
Use the minus sign (-) to specify polling operation under Microsoft Windows 95.
Both sides must agree on using either (+) or (-).
