[net.micro] Need information on 1200 baud modems

sdo@celerity.UUCP (Steve Oualline) (06/14/85)

I am planning to purchase a 1200 baud modem.  
Three brands I am looking at are the
Anchor Mark XII, Volksmodem 1200, and Password 1200.

If you have any experience with any of these please send me
mail.

I have a Volksmodem 12.  Before I bought it I called Anchor Automation and
asked them about the Mark XII and the Volksmodem.  They told that there is no
real reason to choose the Mark XII.  Here are the major differences:

	Volksmodem 12			Signalman Mark XII
	---------- --			--------- ---- ---
	Can send break			Can't send break unless you ask for one
					that has this bug fixed

	Obeys DTR ( switch setable )	Ignores DTR

	Not as many lights		More lights

	$175 to $200 in Byte		$229 to $250 in Byte

Unless you like spending more money, or really get into lights, you can
probably eliminate the Mark XII.

I know one other person with a Volksmodem 12.  He has not had any problems.
My only problem has been with line noise.  I don't know yet if it is my phone
being noisy, or my modem being sensitive, or both.  I will try it from some
some other phones someday ( It is not too bad, since it seems to be only at
my end.  I will see some garbage on the screen every minute or so, but it is
not sent to the other computer, so I can just ignore it.  I listened once on
the phone and actually heard some noise, so I am inclined to blame the phone
for now.  By the way, it only happens at 1200bps.  I suppose this tells me
something, but I don't know enough to know what! ).

The connector on the back of the Volksmodem 12 was a bit of a pain.  It is
a 5 pin DIN connector ( I bought mine without cables ).  I was not aware that
there are at least two different kinds of 5 pin DIN connectors, so I bought
the wrong one when I first tried to make a cable ( they are the same size,
they just space the pins differently!  It is real annoying... ).

I don't know if you want compatability with Hayes or not.  The Volksmodem
12 works OK with MacTerminal, which expects a Hayes compatible.  That is,
if I tell MacTerminal to dial, the number gets dialed.  There is something
not correct, though, because MacTerminal complains that there is no modem
connected, and aborts the dialing.  But the other end is connected at this
point.  I haven't looked into it in detail, since it works.  Other commands,
such as hanging up, work fine.

The Volksmodem 12 is missing some features, such as multi-number memory.
It has a command to repeat the last command, so lack of memory is not a
pain for the common case of redialing a busy number.  I think the lack of
memory is easily offset by the lack of price.

I don't know much about the Password, except that if you are using an Apple
computer it should work, since I have heard that the Apple modem is just
a Password 1200 in a different package ( I don't know if this is true. ).
