type to use on the specified ports. This is used in the
following manner: /H range, hs where range specifies the

Note:
Configuring and Installing NEWCOM.SYS
To load the Serial Solutions for DOS device driver an entry
needs to be added to the CONFIG.SYS file. Any simple text editor,
EDIT for example, can edit the CONFIG.SYS file for example. The
installation procedure given below is for a PCI Quad RS232 as
COM 5 - COM8 and a PCI Lynx 8 Port RS232 as COM5 - COM12
The parameter required by the NEWCOM.SYS driver are
those returned by the BBCARDS.EXE application earlier. A brief
explanation for the parameters required by NEWCOM.SYS follows:
Port Address.
/A5-8,0140
RS232 DTR/CTS - The PC only transmits
when CTS is input true. When the PC is able to
receive its sets DTR output true. The DSR and
DCD inputs are ignored. The RTS output line
is set true just in case the external serial device
needs a true signal.
3 Wire Handshake - Really no handshake at all
since the PC transmits irrespective of the
handshake lines. The 3 wires are TxD, RxD and
Ground, no other lines are required. Thus the
CTS, DSR and DCD inputs are ignored. The RTS
and DTR output lines are set true just in case the
external serial device needs a true signal.
If hardware handshaking is not specified in the
NEWCOM.SYS parameters, type 4, 3 Wire
Handshake is selected automatically.
