Specifying "COMP=n" means that uncompressed data sent to the client will be compressed. If the data to
be sent to the client is already compressed then the data is sent as is unless the client has indicated that
it does not support that compression algorithm.
9.4 Usage of Shared Devices
To use a device on a remote Hercules instance, instead of specifying a file name on the device state-
ment, an IP address or a DNS name is specified.

9.4.2 Parameter
loc_devnum
This specifies the device address on the local Hercules instance.
devtype x
This is the device type.
host
This specifies the host name or the IP address of the system where the Shared De-
vice Server is running.
port
The port number on which the Shared Device Server is listening. If the port number
is omitted then the default port (3990) is used.
rem_devnum
This is the device address of the device on the remote Hercules instance. If the re-
mote device address is omitted then the default is the current device number on the
local system.
COMP=n
This keyword requests that the data has to be transferred compressed between the
client and the server. The argument n specifies the compression level (1-9). A
value closer to 1 means less compression but also less processor time to perform
the compression. A value closer to 9 means the data is compressed more but also
more processor time is required to compress the data.
