PCI DUAL RS232
Type 4
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 Dual RS232 as COM
5 - COM6.
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.
/A5-6,0140
COM ports 5 and 6 are defined, with an i/o address range
that begins at 0140h with the next port having an i/o address that is
8 higher than the previous. i.e. COM5 has an address of 0140h,
therefore COM6 will have an address of 0148h.
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.
