Subject: Re: MDM724 update
Ron Fowler has not released his program. It will have a different
name, more features and be easier to configure.
I have uploaded MDM724, the latest version in the MDM7xx series,
to SIMTEL20 (and also temporarily available on MIT-MC in directory
AR100:FJW; ). You asked what was new... here's the information.
I see no reason to get upset when people update a program to make
it better, if you chose to stay with an older version, that's
your decision. I like the new features.

TOPIC: MDM724.ASM MODEM PROGRAM
FROM : IRV HOFF W6FFC
DATE : 17 FEB 84
NOTE: This program when assembled is 72 sectors
long. Use this figure when merging the
appropriate overlay file for your computer
via DDT, etc. (Most of the overlays were
written when MDM7xx.COM was only 66 sectors
and the example included in each says to
store 66 sectors.) For MDM724 use:
B>SAVE 72 MDM724.COM
NOTE: M7LIB.COM is a rapid and surprisingly easy
way to quickly change any entries in the
phone number library. See M7LIB.DOC if
instructions are needed. M7NM-6.ASM is
necessary for setting or altering numbers
for 'SPRINT', 'MCI', etc.
NOTE: If using the phone number overlay to change
the phone library numbers, be sure to use:
M7NM-6.ASM
(Previous versions of M7NM will not work with
this new version, as the phone number library
now contains 36 numbers (A-Z as usual plus 0-9)
rather than the 26 in versions prior to MDM722.)
Most users will not need the lengthy (160k) source code at all.
Just get MDM724.COM and then check one of the associated over-
lay programs to obtain the overlay for your particular computer.
Merge that with MDM724.COM according to the instructions near
the start of the overlay file, using DDT.COM, etc. (See above
note relative to saving 72 sectors. STAT.COM would then show
144 records for 18k.)
The following bytes can be changed easily with DDT, then Save 72
0DFEH - HEXSHOW 00 = do not show hex record count
FF = show both hex and decimal count
0DFFH - SAVSIZ 20 = 4k file transfer buffer size
(see table below for other options)
0E00H - NUMBLIB (start of telephone number library)
To change the file transfer buffer size via DDT, change byte 0DFFH:
10 (hex) = 16 records = 2k
20 (hex) = 32 records = 4k
40 (hex) = 64 records = 8K
60 (hex) = 96 records = 12k
80 (hex) = 128 records = 16k

RECENT CHANGES:
(READ THE UPDATE HISTORY IN MDM723.ASM FOR MORE DETAILED INFORMATION)
MDM724 - added 10 function keys for auto-typing preselected messages
MDM723 - alphabetizes the phone library vertically for:
'CAL' - used with auto-dial modems including PMMI
'NUM' - used with manually-dialed modems
MDM722 - phone number library now has 36 entries rather than 26 (has
A-Z as usual plus 0-9). Better supports single-digit result
codes for the Anchor Mark XII modem as well as Hayes and USR.
MDM721 - makes it easier to abort an auto-dial call with CTL-X.
MDM720 - changed from BIOS to BDOS call to run the printer.
MDM719 - modest changes, PMMI pulse dialing set faster.
MDM718 - now supports the Anchor Mark XII modem. Buffer size for ASCII
capture set for 16k. Buffer size for file transfers adjustable
from 1 sector to 16k. (Allows for slow floppy disk systems so
XMODEM does not show a timeout error.)
MDM717 - Log-on now works properly on main frames that echo characters
with parity set.
