CTS Serial Port Utility Description
===================================
The CTS Serial Port Utilities (SPU) is a collection of DOS software
utilities that provide you with control over the serial ports in
your computer. Most serial port problems can be resolved by using
these utilities. Each of the utilities support all standard and any
user-defined serial ports. Each of the utilities can operate as a
Windows or OS/2 DOS application.
PortInfo is a comprehensive utility which tests your system to
determine everything possible about your serial ports, including
interrupt and addressing conflicts. PortInfo provides you with
FAILURE and WARNING messages about actual and possible conflicts.
PortInfo provides details on the following:
* Detects multiple serial ports at the same address
(eg, 2 Com1 ports)
* Serial ports that have failed
* Interrupt conflicts between a mouse and a serial port
* Mouse / Modem conflicts
* Shared interrupts (2 serial ports, or a serial port and a
serial mouse sharing an IRQ)
* Conflicts between COM4 and 8514/A compatible monitors
* Unusual BIOS serial port setups
* Serial ports that cannot generate interrupts
* Helps to determine when interrupts can be shared
* Checks and suggests changes (when required) to the
Windows port setups
Other information provided:
* Actual IRQ used by each port and the current IRQ status
* DOS port assignments (com1-com4, mouse)
* Detects which ports have modems or FAXmodems connected, and
(in many cases) if the modem is internal or external
* Detects which FAX classes are supported by the modem(s)
* Port (UART) Identification (8250, 8250A/16450, 16550,
16550A, 16650, 16750, ESP, HSSP, the T/Port, and some
"emulated UARTs"
* FIFO status: If it exists, on / off, else 'None'
* If the FIFO is ON, the current FIFO receiver trigger level
is displayed (includes support for larger FIFOs available in
the 16650 & 16750 UARTs)
* All programmable port parameters: speed, format, parity,
current RTS and DTR settings
* Current status of modem lines: Ring Indicator, Carrier
Detect, Clear to Send, Data Set Ready, with indication
of when the lines are tied together (looped back).
Additional features:
* Can update the system BIOS to accurately match the actual
serial port setting.
* Ports are COMPLETELY restored to their original settings
* Supports standard serial ports 1-4 on PC/AT, 1-8 on PS/2
* Supports up to 8 user definable serial ports (*any*
serial port address and IRQ)
* Displays detailed messages about conflicts with reference
numbers to assist looking up the detailed assistance in the
User Guide.
Special Utilities:
* Update the BIOS data area with accurate port information
* Reset the modem to a known state
* Hang up the modem when left on line by another application
* Control the 16550A FIFO trigger level
* Set port speed and format
* Add or swap serial ports in the BIOS Comm Port data area
* Control the RTS, DTR, and Out2 (IRQ enable) lines
* Reset a serial port to initial settings
CTS Serial Port Utility Registration Options
============================================
** Personal **
--------------
This is the most economical registration for a single user. If you need
to use (or used) the SPU to diagnose a problem with your personal
computer, then this is the license for you. By registering, you obtain
personalized support to assist you with trouble-shooting your computer.
Details are provided in the User Guide section titled "Customer Support
Policy". As part of this license, you also receive:
* Additional features in PortInfo includes the Windows Setup
Verification test that makes sure that Windows is setup
correctly. PortInfo suggests specific changes if any are
required
for your computer.
* BIOS_Fix includes the Windows Setup verification
* 30 minutes of personal assistance with your serial port problems -
you talk to a programmer!
* The most current version of the CTS Serial Port Utilities.
* A FREE CompuServe IntroPak which gets you online with CompuServe
without the regular signup fee plus a $15 usage credit.
* Announcements about updates.
* Special savings on other products from CTS. Details are listed just
before the order form!
The license provided with this option allows the registered user to use
the SPU on any computer personally owned or used exclusively by the
registered user.
** Personal PLUS **
-------------------
This registration option provides all of the benefits above plus:
* A new step-by-step guide to installing a modem. This informative
document will help you make the right decisions about organizing
your serial ports and IRQs when you are installing or upgrading
your modem.
* The serial port troubleshooting guide. This helpful document will
help you resolve the most common types of serial ports problems.
* A printed copy of the attractive 86 page, 8.5 x 11" User Guide,
including 30 pages of introductory and reference information not
included in the electronic manual. This additional information
includes serial port basics, types of serial ports, when and why
you need a 16550A UART, how and when you can share interrupts
between serial ports, details of the RS-232 interface, cable
wiring, and how IRQ 2 and IRQ 9 are used.
* 60 minutes of personal assistance with your serial port problems.
* The MouseOn and MouseOff utilities. The "mouse utilities" allow a
mouse and a modem to share the same interrupt when running under
DOS.
The license provided with this option allows the registered user to use
the SPU on any computer personally owned or exclusively used by the
registered user.
** Professional **
------------------
This license is for consultants and corporate support specialists who
routinely deal with a multiple computers. Treat the SPU like your
screwdriver - that is, as long as it is in your possession and not
"left" (installed) at any other machine, you are in compliance with the
license. Only one individual is authorized to call for support.
This license option provides all of the benefits described above, plus:
* A number of new "advanced options" are available in the PortInfo
utility designed specifically for the technical user. These include
the ability to create fully automated batch files to operate
PortInfo, a configuration file which allows operation without
command line switches, and the ability to force or suppress
different tests. See the "Advanced PortInfo" section for more
details.
* The bonus utility "FindCOM" which locates any serial port installed
in the computer system. This utility does a "safe search" of the
I/O address area to find any 8250 compatible serial port at *any*
address. A very handy utility for those "unknown" machines.
* 90 minutes of technical support (one authorized caller per license)
* Allows use of the SPU on multiple computers AS LONG AS the SPU is
