with

a

wiring diagram

for a custom

ca-

ble!

At $149.95,

not everyone

will

rush

out

to buy one,

but

if you are

spending a

fair amount

of time perusing

manuals to

find pinouts

so you can

wire

up

a custom

cable, this

gadget

will

save

a

considerable

amount

of time

and effort.

My only

complaint

with the

Model

SC21Plus

is that

there should

be

a DB

-9

adapter

available

for it (or

supplied

with

it). Ever since

the

IBM

AT showed

up

with this connector

on

its serial

port,

every

new

286 and 386

followed

suit.

These adapters

are available

from other

sources,

but

it

would make

more sense

for IQ Tech

to ensure

the overall

applica-

bility

of their

product.

The

company

also

supplies

several

Smart

Switch

Boxes

which let you

share

printers

and

/or mo-

dems

between

two

systems

(and contain

the same "smart"

circuitry

that

the

Smart

Cables

do),

and an

interesting

test-

er called

the Smart

Data

Meter.

One of

the real

killers

in serial

interfac-

ing is determining

not only

that

the serial

port

is actually

outputting

data,

but that

the parameters

of

this data

(speed,

pari-

ty, data

length,

and start

/stop bits)

actu-

ally

match up

with what the

receiving

ma-

chine

expects.

If any of

these parameters

differ

between

the two

systems,

data

transfer

will not take

place,

even though

a link

is

established.

Just

as the

Smart Cable

series helps

solve

cable

mismatch

problems,

the

Smart

Data

Meter 931

can

help you

de-

termine

whether

there

is a parameter

mis-

match.

The unit

can be

used

in either

of

two

ways. You

can

hook

it up to

a serial

output

port

and, by pressing

a membrane

switch

to select

various

menu

items from

its LCD

"billboard"

display,

read out

data

values being

output

from the port.

Or,

if you're

not sure

that the

settings

on

a printer

or other

serial

peripheral

are

correct,

you

can use

the

Model

931 as

a

test pattern

generator,

again

setting

vari-

ous parameters

with the membrane

switch.

The SMD931

doesn't

have the

almost

universal

applicability

of the

other

IQ

Technologies

products.

And at

$399,

you'd

have to

be pretty

deep

into

trouble-

shooting

to cost

-justify

it. But

if you act

as a

PC coordinator

for a company,

do

much consulting,

or are

a service

tech

for

a computer

store,

you

really

should take

a

look at

this device.

Users

groups

might

also

want to purchase

a

unit

for the

use of

its members.

I like the equipment

I've seen

from

IQ

Technologies,

and

I

look forward

to

receiving

its

newest

product, a "smart"

printer

buffer

/pro-

tocol converter.

Making

Letters

In the

last year

or so,

I've

really

gotten

in-

to

Desktop

Publishing.

This

interest

came

about

as a

result

of a private-

distri-

bution

newsletter

I publish.

The

first

is-

sue

was 20

pages

and

was done

as

two

separate

documents

on a

Mac using

PageMaker

1.2

(which

has

a 16 -page

length

limitation).

The second

issue

was

44 pages,

and

three

separate

documents.

Issue

number

three

came

after

I up-

graded

to PM

Version

2.0.

Though

it

was

only

36 pages

(the

new

version of

Page-

Maker

allows

128 -page

documents)

my

512K

enhanced

Mac

ran out

of steam

at

page

27,

giving

me a "Memory

Full"

message.

Issue number

four is going

to be

done

on

my ITT

XTRA,

which has

1.5

megs of

RAM

and an

80 -meg

hard disk,

using

the IBM

version of

PageMaker.

This

should

take

care

of some

of

the

problems.

In the

interim,

however,

I've

also

lost use of

both

an

Apple

LaserWrit-

er

Plus

and a QMS

P5800+

I had

been

using

with

the

Mac.

Both

of

these

are

PostScript

printers,

and

I'm going

to

really

miss

them.

PostScript,

in case

you've

somehow

missed

it,

is a page-

description

language.

Its

main benefit,

at least

as

far as

I'm

concerned,

is that

once

it has

a (mathe-

matical)

description

of a particular

type-

face,

it can

generate

that

typeface

in any

size

and

weight. For those

of

you

who

have been

playing

with Hewlett-

Packard

LaserJets

or other

laser printers,

this

means

that you

don't

have to

have

16 dif-

ferent sizes

and

weights of

a typeface
