Lava Computer DSerial-PCI/LP Card - Manual (Page 6)

Unless you already have more than 4 Com Ports installed in your
PC, Windows will by default configure the DSerial-PCI
as Com5
and Com6. If you wish to change the Com number of either one
of the ports on the DSerial-PCI
(e.g. Assign Port 1 to be Com 3),
please use the Lava Com Port Redirect Utility included in the
“Utils“ subdirectory of your Installation Diskette. This may be
necessary because some communications applications programs
do not recognize port designations beyond Com 4. The Lava Com
Port Redirect Utility will allow you to change the Com numbering
of your ports without changing I/O address resources.
To install the Lava Com Port Redirect Utility on your hard drive,
insert the Installation Diskette into your floppy drive, click Start,
Run and type A:\Utils\Setup.
