Well, I started this thread, so I guess it is about time I summarized what I
have learned.
I have an A2000 with a GVP 3001 28 Mhz 030, 4 Meg of 32 bit ram, 2 meg of chip
ram, and 2 meg of 16 bit ram. I recently bought a PPI 28.8 V.34 modem and now
have a cslip account at a local Internet Service Provider (ISP). I was
initially using the serial port to connect.
With the standard serial.device I could connect periodically at 28.8. But
during net transfers, especially ftp's and mosaic stuff, the Workbench became
practically unusable. For instance, I might click on drawer icon and have to
wait 20-30 seconds for all the icons to show up. There was not much difference
between a DTE speed of 56K and 32K, both slowed down the machine terribly.
Then I remembered that when I bought my Bomac Tower (from somebody here in the
forum) I received a Multiface II card. I remember the seller telling me he was
not sure it would work. I tried it one time in my A2000 and could not boot the
system, so I just put it in a box. Well, I decided to dig it out and give in
another try and low and behold it works. The docs where in German, (I lost the
translation) but installation was fairly straight forward. I now have the
Multiface serial rate set at 56K and its serial buffer at about 130K bytes.
While the Workbench is still considerably slower during network transmissions,
it is at least usable. For instance my SYSTEM: partitian, which has 32 drawer
icons in it, takes about 6-7 seconds to open up, compared to 2 seconds when the
duart.device (Multifaces serial device) is quiet. Not great, but usable.
Also, before I switched to the Multiface, the interface of AP was extremely
slow when connected at 14400 baud (19,200 DTE). Now AP's GUI runs quickly and
smoothly.
CONCLUSION: If you want to use a high speed modem with an A2000, you NEED a
serial port card.
