LinkRight 1.1C Beta Patch
This patch is a beta patch. Although most things work well,
there are some things in 1.1 that get broken by this patch.
Serial ports won't work if you install this patch.
There is no corresponding DOS version.
Autostart is disabled in this patch.
As soon as I get good feedback on this patch plus fix the
things that got broke, I'll release version 1.1C.
Users who have had trouble establishing a reliable parallel
port connection with LinkRight should get and use this patch.
This patch should work much better on those systems.
The zip file should unzip to 3 files: LR11C.EXE, LRPAR.SYS
and this file, README.TXT. Unzip it to your LINKRT11 directory
and then run LR11C.EXE. This is a patch to LinkRight 1.1, so
if you have the A or B patches already applied, you'll have
to get your original 1.1 diskette put the LR.EXE and
LRCLONER.EXE from your 1.1 diskette into your LINKRT11
directory before running LR11C.EXE. You may have to change
the settings of the LinkRight 1.1 object on your desktop to
make sure it executes LR.EXE rather than LRBAK.EXE.
LinkRight 1.1C will be displayed as the version when you get
the first window with the options of Local or Remote so be
sure to check for it.
I assume you can figure out where to place the included
LRPAR.SYS.
Turbomode (in the Options menu of LinkRight when in Local mode)
should be turned off initially. Also, Turbomode is read and
set once when you establish a connection. To change Turbomode,
change the option, disconnect if you are currently connected,
and do a re-connect. If you have no trouble with Turbomode
off, you can try Turbomode on and get a speed boost.
The LinkRight parallel port driver can now be used in interupt
driven mode or polled mode. The default is polled, which matches
the default of PRINT01.SYS in OS/2 Warp 3.0 (or so I've been told).
Interupt driven mode has some problems. I've had some of my test
systems lock up completely when used in Turbomode with interupt mode.
The same system does not lock up when Turbomode is off. None of my
test systems have any problems when using polled mode. Many
gigabytes transferred successfully!!
For LRCLONER, you no longer need EAUTIL.EXE and CMD.EXE in the
C:\TEMP directory. This should make cloning easier. You still
need the temp directoy and LRCLONER.EXE should be started from
this directory.
The complete list of options for LRPAR.SYS are
DEVICE=LRPAR.SYS /Q:7 /P /A:3BC /M
where:
/Q:7 uses IRQ7 or /Q:5 uses IRQ5. These are the only IRQs supported.
Interupt driven mode can only be used if PRINT01.SYS or PRINT02.SYS
also uses the same interupt. If no /Q option is selected, polled is
assumed.
/P is for polled. This is a useless option, since it is the default.
/A:3BC or /A:378 or /A:278 select the address of the LPT port for
LinkRight to use. If this parameter is used, only one address can
be specified. Then, when you select Connect from the LinkRight
menu, no matter which LPT port you select, either LPT1, LPT2 or
LPT3, LinkRight will use the address specified. If this parameter
is not included, LinkRight reads the BIOS info at bootup time to
get the LPT addresses.
/M is to specify MicroChannel machines. For some MicroChannel systems
when booted from bootable floppies, LinkRight would not see that it
was MicroChannel and would assume an ISA bus. This caused the
driver to fail. So if you boot your MicroChannel system from floppies
and the LinkRight driver displays a message at bootup time saying
an ISA bus was found, use this parameter to fix the problem.
The preferred and suggested mode of use is no parameters on the
LRPAR.SYS line in CONFIG.SYS. You can add parameters if there are
any problems.
I'm interested in hearing speed test results on various systems. A
quick note would be appreciated. A good test is a 1 megabyte file.
Note that a group of files with a total size of 1 megabyte will be
significantly slower since there is a lot of overhead for each
individual file.
For the 1 megabyte file on various systems you should expect these
kinds of times. Note that the processor mentioned is for the receiving
system and as long as the sending system is close to the speed of the
receiving system, the receiving system will be the bottleneck.
Please let me know if you get significantly different numbers.
386 SX 16 Mhz 50 seconds
486 SLC 25 Mhz 25 seconds
486 DX 33 Mhz 15 seconds
Pentium 60 Mhz 10 seconds
These numbers assume 8 bit mode (look at the Remote system when you
establish a connection and it will tell you if it is using 8 bit
mode or 4 bit mode; LinkRight figures out fastest mode it can use
automatically). Expect 30% slower for 4 bit transfers.
Also assuming 1024 packet size and Turbomode.
Expect broken features fixed soon and more new features in the next
few weeks.
Good luck and happy computing!!
