[comp.sys.ibm.pc.hardware] Problems with Logical Connection Plus

We're having problems with our two Logical Connection Plus machines. 
First of all I'd like to know if anyone knows the fax number or uucp
mail address for Fifth Generation Systems.

And now to the problems:

The two LCPs are connected to each other via the network cable.  There
are two printers and six PCs connected to them, the printers and one
pc are connected via Centronics and the rest 5 PCs via RS-ports.  All
the ports have been configured with overraid feature because the LCPs
'smart' self configuretion didn't seem to work correctly in all cases.
One of the printers (Canon laser) is configured as default connection
for all of the PCs.

I'd be grateful of any information concerning the following problems:

Problem one: Whenever LCP is reseted, it sends garbage to both of the
printers, and both printers must be soft-reseted by hand after that.
Is there any way to stop this?

Problem two: Whenever the PC that is connected to LCP via Centronics
cable is turned off, the LCP starts to receive continous data from it's
port, and starts to send it to printer. This data consists mainly of
line feeds. The problem disappears if either end of the Centronics
cable is disconnected (the LCP end or the PC end).

Problem three: One of the LCP ports is connected to Decserver, in
order to use the printers from our lan. The LCPs soft handshaking
doesn't seem to work at all. Small prints (a page or so) go through
all right but if the file is a bit larger the LCP refuses to inform
the decserver that it's not ready and the rest of the file gets lost.
Moreover, when our mainframe notices this, it tries to send the file
to LCP again and again, resulting infinite attempts to print the same
file and always getting to the same page.

Problem four: This may be a coinsidence, but we've noticed that ports
number three and six on both LCPs produce much more errors than the
other ports. In fact, a PC connected to port three on either of the
LCPs can't even read the configuration of the LCP.
