Choose the ZyXEL ISDN together with the ZyXEL SP111AT, where you can use both
the serial and parallel port of the ZyXEL. The parallel port (on the SP111AT)
card can let the parallel port emulate a serialport (without any drivers), so
you can get FULL speed of your ZyXEL ISDN product (up to 921.600Bps).

How does this work? After all, some software on the PC has to be pointed to the
interface which is its connection to the ZyXEL. Presumably, that would be one of
the PC's parallel ports. What software is smart enough to use a parallel port for
ISDN use that doesn't need a driver to fake it out?

I haven't tried it yet, but a couple of Kali players recommended the
Hayes ESP Serial Card. It offers a full 1K buffer as opposed to a 16
byte buffer on a standard 16550.

The BSP will 'talk' to a com port higher than 115200.
I am using the Digi AccelePort c1 w/ beta win95 drivers at 230400 to
the BSP with noticeable improvement from 11.1k to 14.5k on my ISP's
ftp site.
The @P2=115200 on BSP needs to be changed to @P2=230400.
I used HyperTerminal to set and save this setting.
A word of warning though, ISDN Surfr Setup will not 'see' the BSP at
this speed and will have to be set to 115200 if reconfiguration is
needed.
I understand that the Hayes ESP Accelerated Com card will also work.

1. Besides Hayes, Boca (www.boca.org) has IO650 board which supports 230kbps
async rate. It uses 16650 which is an updated version of 16550 with 32byte
FIFO. Both Hayes and Boca are available from www.necx.com.
2. SMC (www.smc.com), the company who makes Super I/O (and now Ultra I/O) chip
that goes into the motherboard, now has new chips that support 230kbps.
I guess the other competitor, UMC, also has a new product line. This means
that many newer Pentium/Pentium Pro motherboards will have the 230kbps
capability built-in, although whether the standard drivers can support
it is another question.

Gene, thank you very much ! I had given up on this long ago, and after
reading your reply, I decided to try one more time to get my BSPro
going at 230400.
With the info you posted I managed to make it work and have seen dnld
rates over 15K/sec as reported by WS_FTP32 when connected to
ftp.microsoft.com !!! A vast improvement over the 11K/sec I was
limited to before.
For other suffering BSPro users out there, I'm using a BOCA IO650 with
drivers for a CHASE RESEARCH IOXTRA for Windows95 (couldnt get
the driver that came with the BOCA to work and the card appears to be
the same as the one CHASE sells).
Again many thanks....

Lava Link makes a 430.8Kbps serial card. Drivers only for Win 3.x and Win
95 (no DOS or other OS's, yet).
It uses a faster clock rate 4X faster then 16550 cards.
It uses a 32-byte buffer instead of the traditional 16-byte buffer that
limits most other cards at around 250Kbps (Hayes, etc..)
List price is $59.95

You'll get much better performance all around by installing an inexpensive
Ethernet card in your PC, and adding an ISDN router outboard. Win95 does
an excellent job of supporting IP over Ethernet with a wide range of
adapters. Routers that support Ethernet to ISDN can do a great job of
making full use of the ISDN bandwidth when allowed to talk at Ethernet
speeds on the other side. Use of a TA and serial port does result in
high interrupt rates on your PC.
Using a router can involve a few more steps, but the results can be worth
it. If you have a second PC in the house, it's quite worth it to have them
networked and have a separate router providing your connectivity out.

I have a Hayes ESP 2 single port board. It works great under
Windows for Workgroups 3.11 with the latest drivers from Hayes. This
should be a great card to use with a ZyXEL Elite 2864i and ISDN.
I haven't tried getting my ESP 2 working under Windows 95 yet.

Actually, the Hayes ESP II Card uses a 1K receive and a 1K send buffer. It
supports speeds up to 921K. Has DOS, Win3.1x, Win95 and OS/2 drivers.

Who needs drivers, if the speed are based on a fastere clock ?????

The ESP II boots up in a mode compatible with a 16550, i.e., with the
buffers sized at 16 bytes rather than 1024.
Other interesting features of the Hayes ESP cards include the ability
to use DMA for data transfers, which lowers the load on the CPU, and the
ability to operate without an interrupt vector. At least the first
capability requires installation of a driver.
I used two dual port ESP II cards under OS/2, and was quite pleased
with their performance. However, I switched to Windows NT, for which
there are no drivers.
