NPCP
To use NPCP, you must load the program MININET.EXE. You can install this
program by inserting the following statement into the CONFIG.SYS file:
INSTALL=MININET.EXE
or by placing the following statement into the ROMINIT.BAT or
AUTOEXEC.BAT file:
<path>\MININET.EXE
Where:
<path>\
is the drive letter and pathname where MININET.EXE is located.
TTY
To use the TTY protocol, the NRTTYM.TBL file must exist in the current
directory or in the Path. NRTTYM.TBL is the modem table. For information
about creating a customized modem table, see the
PSMDM0C, DOS HHC
MODEM TABLES
product, P/N: 215Ć968Ć001.
If the application uses NORMOD.SYS or NGENMOD.SYS to support PC Card
modems but uses different command line settings than the default Norand
Utilities configuration, the command line for the driver must include
ćNMODEMn" where n" is the COM port number used by the driver.
NRInet Using PSROM0C Version 3.xx
To use the NRInet protocol version 3.xx, the PATH must include the directories
of the following drivers:
"
PKODI.COM
"
ODIPKT.COM
"
LSL.COM
"
RS485ODI.COM
Optionally, configure a DHCP server to provide IP information required by the
computer, such as the IP addresses of the client, server, router and domain name
servers.
The NET.CFG and WATTCP.CFG files are overwritten by PSROM0C.
Some computers support two network interfaces for NRInet: Ethernet and
RSĆ485. The network interface is selected in a menu in Norand Utilities during
the IPL sequence. This setting is stored on the RAM drive so it is lost any time
the RAM drive is removed or formatted. For example, applications that boot
from a PC Card often format the RAM drive before installing the application. In
these cases, return to the Norand Utilities menu to reselect the setting in order
for NRInet sessions to work correctly.
NRInet Using PSROM0C Version 2.xx
To use the NRInet protocol, the PATH must include the directories of the
following drivers, which are loaded and unloaded by PSROM0C.EXE:
BOOTP.EXE
DHCP.EXE
ETHDRV.EXE
INET.EXE
LSL.COM
ODIPKT.COM
PKODI.COM or RS485ODI.COM
BOOTP.EXE and DHCP.EXE are required only if IP information is to be
retrieved from a BOOTP server or a DHCP server as described below.
PSROM0C.EXE executes BOOTP.EXE first. DHCP.EXE is executed only if
BOOTP.EXE fails.
