Some technical questions on the TI - PC

1) does anybody know of a utility, mechanism, consultant or person
who will recover at TIPC Winchester disk that lost its VTOC.
Somebody lost a VTOC from some weird EASYWRITER bug here and they
have a lot of programs and files on it and of course they don't have
any backup.

2) does anybody know how to get documentation on how to program the
graphics board from MS-FORTRAN or MS-PASSCAL.  (We have three plane
graphics boards here.)

3) is there any documentation available on the modem card.
We have ttycom but we wish to be able to access it from our 
programs.

4) THe installation guide for the serial card says the thing supports
SDLC type protocols.  There is no documentation on this feature.
Does anybody know anything about it.

We have installed about 88 TI PC's here at SMU (some of which were bought
for personal use in a mass deal.)  These are outstanding questions
which we have not yet found an answer.

In answer to your question 3 on the modem, you can access
the modem from your program if you use the Async Comm
Support software from IBM. The driver routine (RS232INT.BAS
or RS232INT.EXE) is an interrupt driven routine with 2000
bytes of receive buffer. I have routines that will interface
this with PASCAL and this works out as a very nice way of
using the interface.
