- SUBJECT : IMP overlay list
-
- FROM : Irv Hoff

- DATE : 01 May 86

-
- IMP is the first (and currently the only) modem program that
- takes advantage of the automatic 1k protocol offered by XMODEM 112 and
- higher, and any KMD program (a replacement for XMODEM). It also is one
- of the few programs to use the automatic stepdown feature of the new
- 2400 bps modems to adjust the computer speed to match that of the an-
- swering system. (The US Robotics only steps down from 2400 to 1200,
- not to 300. The Paradyne ARK, Racal-Vadic 2400, Hayes 2400 and others
- automatically stepdwon from 2400 to 1200 to 300. IMP takes full advan-
- tage of this feature.)
-
- At the bottom of this note is a list of the overlays that are
- currently available for the IMP modem program.
-
- There are a number of options which the user may select to cus-
- tomize IMP to suit his needs. As with nearly any program, there may be
- things you "wish you could do". We tried to cover many of those, while
- still keeping the overlays as short and simple as possible for "most of
- the users". An attempt was made to include enough features to allow
- the sophisticated user enough tools to write his own routines if/where
- appropriate, in the overlay.
-
- Read the IMP.CUS file for notes on how to select/use some of the
- features offered in each IMP overlay. (Such as changing the lead-in
- character for the local commands while in the terminal mode to something
- other than ESC, etc.)

- Others will be added as they are developed. If you have a
- computer not already mentioned, you can perhaps use one of
- the above that matches your I/O (such as Dart, SIO, 8251,
- etc.) by selecting the correct ports, etc. Otherwise you
- can try calling me at the below voice number from 10 am to
- midnight Pacific, and perhaps we can get something for you
- to use (then add it to this list for others).
