Bunk!  The Plus has the two hardware lines required to support hardware
handshaking.  The 512 and 128 only had one.  Make sure you get a modem
cable that supports both hardware lines though!  Some don't.  I use mine
at 14.4 without trouble.

Hmm.  I've been having trouble getting my Newton to talk to a 14.4 modem that
I borrowed from my dad (the Newton uses Mac serial ports).  I wonder if that
would be related to the Mac modem cable I bought for it.  It can get the modem
to dial, but once connected I can't get it to do anything.

Newtons are notoriously fussy about what modem they will talk too.

My approach is to write scripts in my terminal software to do the dialing,
not using the Newton support.  Doesn't help when I want to fax, thuogh.  You
might want to play with your AT settings... maybe get as connected as you can
with a PC, then hang up and read your modem settings with AT&V.  Then either
make those powerup default, or else write them into your dialog with your
Newton.

14.4 or 28.8. All will have hardware handshaking which should work with your
plus you could send them a note at lynx http://www.supra.com to find out. 
The supra has a flash rom capability in teh more expensive version. So  do
others. You need to talk to a modem maker to find out how much capability your
computer can utilize. 14.4 non flash rom are now less than $100. and flash rom
is pretty much for evolving technology. the 14.4 is already solid. try http
://www.usr.com for us robotics.

I bought a 'surplus' "GlobalSwitch" - a device for using a modem on a
digital or PBX (etc) phone system. It goes between the handset and the
phone base, and one's modem plugs into it. I don't have a Global modem,
however, so have tried it my Mac PowerBook and Supra 144LC, on a Meridian
'Voice Mail' (UM) system that uses ComDial phones. Well, I couldn't dial
Grex with it, using just manual dialing from my Mac: it did not dial
through.  I pre-dialed on the phone, and then tried to connect, and it did
give me a CONNECT, but nothing after that. Can anyone shed any light on
where the problems might be, and suggest a trick to fool the GlobalSwitch
into thinking a Supra is a Global (if that is the problem....)?

I tried atx1dt, per GolbalSwitch instructions (x3 for the supra just
detects BUSY). Dialed, but it did not get ringing from Grex - just a pause
and then a busy tone (but Grex wasn't busy). I suspect this gadget talks
to the Global modem, or vica versa, in a language Supra does not
understand. Is this likely/possible? There is a "Setting" switch on the
Switch, with positions 1 to 4, and it is supposed to change how loud the
dialtone is on the telephone handset, but it doesn't. It may be that this
telephone base is just incompatible (they provide a long list of Settings
for different phones, and several are noted as "may require custom factory
setting", or "not campitable", or "nonstandard handset wiring" - the
Comdial is listed as compatible, but maybe not *this* Comdial in this
PBX). I'll try it on standard phone, and maybe on a different PBX.  There
is still some utility in being able to put the modem on a set when it is
permanently wired into the wall.

Yes, I used 9! With and without comma - same result. I can hand dial as
fast as I can, and the 9 connects outside, but no outside dialtone is
heard (I've always thought that was interesting).

Odd.
