Baud Clock Control Is At I/O Address 02D0; Newcom.sys Parameters - Brainboxes CC-357 User Manual

PCI Velocity RS232422/485

Baud clock control is at I/O address 02d0

Write 0xf6 for /8 (default), 0xf2 for /4, 0xd6 for /2, 0xd2 for /1.
Note down IRQ and I/O which in this case:
The IRQ = 11
The I/O address = 0140

NEWCOM.SYS Parameters.

The NewCOM.SYS device driver included with the PCI
RS232/422/485 driver software is used to set up the card in DOS
and has the following syntax:
NEWCOM.SYS /A port address, /I IRQ,range /B number buffer /S
buffer /H hardware handshake
Where /A port address specifies COM port number followed by a
hexadecimal address in the form /Ax,y where x is COM
port range and y is I/O address.
/I IRQ, range specifies card interrupt and COM port range. The
COM port range specifies the COM port(s). Range may be a
single port OR a range of ports.
/B number buffer is used to set the number of pairs of
buffers to be allocated to ports and is a decimal number in
the range 1-maxport.
/S buffer Set size of all buffers in bytes, buffer is rounded
to the nearest power of 2 and must be a decimal number in
the range 32 to 32768. For any serial port opened two
buffers of size buffer are allocated, one for input and the
other for output.
/H hardware handshake selects which hardware handshake
type to use on the specified ports. This is used in the
following manner: /H range, hs where range specifies the
COM port or ports and hs selects handshake type.
Handshake types available are:
