PCI 1 Port RS422/485
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 RS422/485 as COM
5.
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.
/A5,0140
COM port 5 is defined with an i/o address of 0140h.
IRQ, Range.
/I 11,5
11 is the IRQ and since the COM port is COM5 is entered 5.
Number Buffer.
/B5
Five buffers are defined, though only Three ports are in use
- this is because buffers in DOS are assigned in a sequential order
from COM1. Since the PCI Velocity RS422/485 has been assigned
a COM port value of 5, all preceding COM ports, must have
buffers assigned to them also.
Buffer Size.
/S512
Buffer size set to 512 bytes.
