Chapter 1 Page 2
NewCOM.sys A device driver, it supports COM1 to COM16,
allowing 16 serial ports to be used under DOS.
It also includes an interrupt handler for
enhanced performance with user definable
buffer sizes. Accessible from all DOS
languages, it is the heart of the Serial Solution.
It has extensive handshaking support,
implementing both hardware handshaking
using any combination of the DTR, DSR, CTS,
RTS, and DCD lines, and a software handshake
using the XON/XOFF protocol.
NewCOM24.sys A device driver providing support for 24 ports.
NewCOM32.sys A device driver providing support for 32 ports.
NewMode.exe A replacement for the DOS ’mode com...’
command. NewMode is used to set the serial
parameters, including the port address, IRQ line
used, the baud rate, parity and data and stop bit
options. Baud rates supported are from 110
baud to 115,200 baud! Included is a very handy
query mode that reports the settings of the
various serial ports. Flexible and fast!
EASY programs. The EASY disk contains short, simple to
understand and use EASYBAS, EASYC and
ASYPAS programs, providing straight forward,
file type I/O to serial ports with debug
information. Use these FIRST, base your
sample applications on them. Source code,
make files and compiled ready to run programs
supplied.
TERM programs A suite of larger terminal emulation programs
written in C (Cterm), Assembly language
(Aterm), Pascal (Pasterm), BASIC (BASterm)
and FORTRAN (FORterm) show how to access
the NEWBIOS routines as well as the simple
file I/O to ports. They contain many lines of
code and are thus harder to grasp. They
