Re: Datalink 2400 internal modem card

Phil,

Good News/Bad News:

Good:
I've got one of these ... and managed to find it (I've just moved house and 
most everything is still in boxes) and have a look at it.

The on-board communications package is accessed (according to the manual) 
from BASIC by:
   1) if you want 80 column, do a PR#3
   2) type "IN#s", where "s" is the slot number the card is in
   3) type "<CTRL>A" followed by "T" to get into "terminal mode"
   4) type "<CTRL>A" followed by "?" to get a "communications menu" that 
lets you select various options

The card responds (again, according to the manual)  to the standard AT 
command set including some of the extended "&" commands.

Bad:
The adapter cable looks simple -- it terminates in a pair of RJ11 sockets 
that are affixed to a PC board and encased in a plastic "shroud" for 
mounting in a slot at the back of a ][+ or //e.  However ... I can see that 
the board has some surface-mount discretes on it but I can't identify them 
or how they're connected.  I tried to remove the board from the shroud to 
get a better look, but it doesn't look like it will budge without breaking 
something. :-(   Unfortunately, all of my test gear is still packed so I 
can't even do a quick continuity check (I'm guessing the SM devices are 
probably just some sort of fuse) to see if the wiring is effectively 
straight-through.

There are a lot of pages in the doc's (70 in the "DataLink User's Manual", 
and 96 in the "Communications Software User's Manual") so It would take me 
some time to scan them.  [N.B., unlike many Apple ][ add-on cards there is 
no circuit diagram that might give a clue to the layout of the adapter 
cable. :-( ]

P.S.
I may try to scan the books and figure out the cable once I'm finally moved 
in [and if I remember :-)]

be seeing you ... Don
