EPSON EPSON AMERICA INC. SERVICE DEPARTMENT PRODUCT SUPPORT BULLETIN DATE: 12/18/87 SUBJECT: Using Lap-Link with the Equity II NUMBER: S-0032 This bulletin describes a problem we've identified in using the Lap-Link data transfer program from Traveling Software with the Equity II computer. Lap-Link is supplied with the Equity LT laptop computer and is also widely used with other laptop PCs. Lap-Link transfers data via the serial ports of the two PCs using a direct-connect cable. It operates at a very high baud rate - in fact, it defaults to 115,200 bits per second. The Equity II's built-in serial port will not operate at speeds faster than 57,600 bps. If you attempt to load Lap-Link with its default settings on an Equity II, the system will simply lock up, forcing a reset. The first (and easiest) way of dealing with this situation is to configure Lap-Link on a different system. You cannot reconfigure Lap-Link on the Equity II because it locks up before you can change the settings. Load the working copy of Lap-Link on another PC, select Options, cursor over to Baud and then cursor over to 57600. Select Save from the Options command line and enter Y_ to the "Ok to save settings?" prompt. You now have a version of Lap-Link that will work correctly on the Equity II. Please note that you will have to set the baud rate on the other system to match. If you have access to an option card with a serial port, you can use it to re-configure Lap-Link. Set DIP switch 2-8 on the front panel of the Equity II to the ON (or UP) position to disable the internal port. Set the option card port as COM1 and install the card. You may then either use the port on the card permanently at 115,200 bps or configure Lap-Link down to 57,600 bps, remove the card and re-enable the internal port. This problem exists with all versions of the Equity II system boards. Once properly configured, you'll find Lap-Link to be a great help in moving data between different systems. Page 1 of 1

PRODUCT SUPPORT BULLETIN

SUBJECT: Using Lap-Link with the Equity II
NUMBER: S-0032
This bulletin describes a problem we've
identified in using the
Lap-Link data
transfer program
from Traveling
Software with the
Equity II computer.
Lap-Link is
supplied with
the Equity
LT laptop
computer and is
also widely used with other laptop PCs.
Lap-Link transfers data via the serial ports of the two
PCs using
a direct-connect
cable.
It operates at a very high baud rate - in
fact,
it defaults to 115,200 bits
per
second.
The Equity II's
built-in serial port will not operate at speeds faster than 57,600
bps.
If you attempt to load Lap-Link with its default
settings on
an Equity II,
the system will simply lock up, forcing a reset.
The first
(and easiest)
way of dealing with this situation is to
configure Lap-Link on a
different system.
You cannot reconfigure
Lap-Link on
the
Equity
II because
it locks up before you can
change the settings. Load the working copy of
Lap-Link on another
PC, select
Options, cursor
over to
Baud and then cursor over to
57600. Select Save from the Options
command line
and enter
Y_ to
the
"Ok to
save settings?"
prompt.
You now have a version of
Lap-Link that will work
correctly on
the Equity
II. Please note
that you
will have
to set
the baud
rate on the other system to
match.
If you have access to an option card with a
serial port,
you can
use it
to re-configure
Lap-Link.
Set DIP switch 2-8 on the front
panel of the Equity II to the ON (or UP) position to
disable the
internal port.
Set the
option card
port as COM1 and install the
card. You may then either use the port on the
card permanently at
115,200 bps
or configure
Lap-Link down to 57,600 bps, remove the
card and re-enable the internal port.
This problem exists with all
versions of
the
Equity
II system
boards.
Once properly
configured,
you'll find Lap-Link to be a great help
in moving data between different systems.
