[comp.sys.mac] Questions about Hayes compatible modems

hoyme@coltrane.SRC.Honeywell.COM (Ken Hoyme) (01/07/89)

I have a couple of modem questions:

1) Does anyone have any experience with the Supra Modem 2400?  I seem to 
   recall some mention of this a couple of months back, but I don't recall
   the particulars.  At $149 it is certainly the cheapest 2400 baud option.
   Is it fully Hayes compatible?  Reliable?  Would anyone recommend any of 
   the other inexpensive 2400 baud modems over the Supra?

2) We have a LocalTalk zone of about 35 Macs.  I am interested in the Shiva
   NetModem 2400 as a possible shared modem.  Can anyone comment on the 
   security provided for call in users?  (I understand it is a password
   system..How secure is it?)  Also, their ads show the ability to have a
   remote Mac dial in using any modem and be able to look like they are in 
   the LocalTalk zone  (print to LaserWriters, use TOPS, etc.)  Has anyone
   tried this?  How well does it work?  Am I correct that the other modem
   does not have to be a Shiva?

Thanks in advance for the info

Re Shiva NetModem:  We have purchased Shiva's NetSerial, to which we
have attached an external 2400b modem (Practical Peripherals).  We
prefer that because it is more flexible; i.e., we can attach a different
modem or different serial device in the future.

It works just fine as shared modem for calling out.  Good product.

For calling in, it works functionally as advertised; i.e., you can simply
print to the laserprinter, etc.  However, be aware that, with a 2400b
modem, the speed to the printer is 100x slower than you're used to on
a direct appletalk (240Kb) link.  That is, it is SLOW!
