[comp.sys.mac.comm] MultiPort Serial Boards?

stui@caladan.wa.com (Stuart Burden) (09/23/90)

I'd like some feedback on NuBus MultiPort serial boards for the Mac.
I haven't been following this type of hardware development at all and
am curious about several things:

 o Is anyone making multiple port serial boards, and if so who?
 o Are they any good?
 o How does comm software interface with the board?
 o Do they work with Apples Communications ToolBox?
 o Are you required to install special inits or drivers other than
   CTB type drivers?
 o Any pricing would also be helpful

Thanks in advance.

Stu.

	There are a number of companies making muliPort cards for the MacII/
Nubus including: Creative Solutions, Taniwha, Tara Systems, Applied Engineering,
Xecom, DigiBoard, and Apple.  I think that's all.

> o Are they any good?
	I have used most of the above, and other than misc. bugs that have 
been correctly pretty promptly, they all seem to work just fine.

> o How does comm software interface with the board?
	In the past, comm software had to be 'patched' to work directly with
these cards either via an INIT, or a binary/resource related patch to let
the program know that it existed.  Also there was 'shadowing' which simply
remapped output to the modem port to a port on the card instead.

> o Do they work with Apples Communications ToolBox?
	All of the cards currently support the CTB, and this is the recommended
solution to using the cards as it is now system support for such things.

> o Are you required to install special inits or drivers other than

	Each card comes with an INIT which simply loads the drivers into the
device table and then registers them with the CTB.  If you do not have the
CTB, then there is more stuff for doing shadowing, etc.

Disclaimer: I have tested and continue to use many of the above cards in my
machines.  I can say whatever I want about them, and let them do as they may ;-)

There are at least two PROJECTS in the works for multi-port serial
NuBus cards, specifically in the area of multi-line bulletin boards.
I'd check with the creators of NovaLink, a multi-line (5+, I'm sure)
BBS program for any NuBus Mac, and also Hermes (currently 2 line,
with plans to expand to more). I don't have a contact for these people, 
but I hope this gives you a lead.

'Tis a poor sort of memory that only works one way...


I *think* that DigiBoard and National Instruments both make multi-serial
port NuBus boards with software.  Check 'em out.
