- May 29,1990 NMODEM 0.91a
-
- 1. Ah Ha! I think killed the Bad Header problem!
-
-
- May 29, 1990 NMODEM 0.91b
-
- 1. Now can transfer files that are multiple of 2048 and it works.
-
- 2. Tweaked the first block interface seems better but sometimes
- doesn't connect.
-
- 3. Bad Header problem seems to be gone!
-
- 4. Receive side user screen improved!
-
-
- 05-31-90 NMODEM 0.91c
-
- 1. Improved receive interface after synchronized.
-
-
- 06-JUN-90 Ver: 0.91d
-
- 1. Corrected File Check routine before transfer.
-
- 2. Added commandline switch for optional DirectVideo.
-
- 3. Improved CommandLine check.
-
-
- 7-Jun-90 Ver: 0.91e
-
- 1. Fix blocksize cosmetics.
-
- 2. Improved Carrier Detect in Receive sequence.
-
- 3. Improved Carrier Detect in Send Sequence.
-
-
- 8-JUN-90 Ver: 0.91f
-
- 1. Improved startup sequence.
-
-
- 09-JUN-90 Ver: 0.91g
-
- 1. Smaller now needs less than 40k to run!
-
- 2. Better startup sequence.
-
- 3. Faster IO and receive sequence.
-
- 4. Improved receive sequence.
-
- 5. Improved handling of Runtime Errors.
-
- NOTE: Due to timing constraints NMODEM will NOT work at 300 Baud!
-
-
- 10-JUN-90 Ver: 1.00
-
- 1. Now should correctly restore modem on exit!!
- [Thanks twc for getting me on track here!]
-
- 2. Finally I feel it can be called version 1.00. The major hurdle
- in item #1 above should make this a fully functional protocol!
-
- 11-JUN-90 Ver:1.01
-
- 1. Added more items to force modem back into mode before NMODEM
- started.
-
- 13-JUN-90 Ver: 1.02
-
- 1. Added code to improve rejection of false CAN byte received.
-
- 2. Changed send abort from keyboard sequence to allow receive
- side to better see the CAN bytes.
-
-
- 14-JUN-90 Ver: 1.03
-
- From this version on I have changed the registration schedule for NMODEM
- since I would like to make a few bucks from this effort.
-
- Drv/Dir/DirectVideo Options will only function in the Registered versions
- of NMODEM.
-
- If you find NMODEM adequate without these options then only $5.00 will
- register the current and all future versions of the "cheapware" issue
- of NMODEM.
-
- If enabling of the options of value, $10.00 will get you a disk with a
- version of NMODEM allowing the options to function plus the latest version
- of NMODEM and NMTERM and whatever I decide to throw in at the time.
-
- SYSOPs I'm sorry if this is a problem but I cannot think of a reasonable
- Zer0 cost way to screen valid SYSOPS for free registered versions.
-
- As the product evolves I'm sure various options will be requested and
- added - if feasible and they do NOT decrease the efficiency of NMODEM.
- I will try to make a reasonable evaluation as to whether the registered
- version or "cheapware" version or both should have that option enabled.
-
- 15-JUN-90 Ver: 1.04
-
- I changed NMODEM so that if Drive, Directory or DirectVideo switches
- are passed they will just be ignored. This if for those users that
- have a program such a TELIX which insists on passing the Drive/Directory
- with the filename.
-
-
- 15-JUN-90 NMODEM Version: 1.05
-
- 1. Removed valid port check problems with newer UARTS.
-
- 2. Changed usage and syncup to show registered status.
-
- 17-JUN-90 Ver: 1.06
-
- 1. Added support for 16550 UART FIFO buffer. The new commandline
- switch /F will turn it on. It is turned off at end of NMODEM run.
-
- 17-JUN-90 Ver: 1.07
-
- NOTICE
- ------
-
- Registered users can now download new versions for free from
- PYSMATIC or THE COMM CENTER see NMODEM.DOC for details!
-
-
- 1. Added MNP support via the /M switch on commandline. NO CRC checking
- will be performed.
-
- 2. Eliminated forced delays in handshaking loops of Send/Receive.
-
- 3. Removed forced delays in SynchUp routine.
-
- ------------------------------------------------------------------------
- CAUTION: Version 1.08+ will NOT be compatable with earlier versions!
- I need to change the NAK handshaking to improve reliability!
- ------------------------------------------------------------------------
-
- 17-JUN-90 Ver: 1.08
-
-
- NOTICE
- ------
-
- Versions prior to 1.08 are NOT compatable with 1.08!
- Sorry for any problems this may cause.
- In non-error conditions pre-1.08 versions will work!
-
-
- 1. Improved error interface is more BulletProof!
-
-
- 17-JUN-90 Ver:1.09
-
- 1. Timeout on syncup adjustment.
-
-
- 19-JUN-90 Ver: 1.10
-
-
- 1. First I must apologize for a gross blunder on my part in the
- method of calculating the CPS. It seems I dropped the decimal
- point figures and as such at 2400 Baud the only rates were 227
- or 256 at the high range. Similiar problems existed at 1200 &
- 9600, etc. The CPS now should be very close to correct! The
- calculation uses rounding so it will reflect the closest even
- value.
-
- 2. Item 1 above means it time to do some fine tuning! As of this
- version the best I can get is 234 CPS at 2400 Baud. Newer
- versions will be accented on improving these numbers.
-
- 3. Corrected CPS calc if CRC error on receive side.
-
- 4. Optimized CRC calculation sequence for more speed.
-
-
- 20-JUN-90 Ver: 1.11
-
- 1. Optimized the main send and receive loops.
-
- 2. The wait for ACK from receive is costing about 2 or 3 CPS, so I'm
- going to try for a send ahead scheme. This will cause 1.12 to be
- a bit unless I find a non-related bug.
-
- 22-JUN-90 Ver: 1.12
-
- 1. Major surgery! Now uses 47K of memory but gained about 3 CPS over
- 1.11 version.
-
- * Implemented partial look ahead scheme for sending.
- * Further optimized the send methods and sequences.
- * added 4k in buffers but managed to reduce some code to keep
- the size down.
-
- 2. This version still ok with 1.10 and 1.11 but much better on send.
-
- 05-JUL-90 Ver: 1.13
-
- 1. Corrected bug in send handling of Bad CRC! from receiver side.
-
- 08-14-90 Ver: 1.14
-
- 1. This version compiled with Turbo Pascal 4.0 to see if it will kill
- some problems with the TP5 compiled versions.
-
- 29-AUG-90 Ver:1.15
-
- 1. Corrected nmodem.log item on size of last block sent or received.
-
- 02-SEP-90 Ver: 1.20
-
- 1. Considerable rewrite of SendFile Procedure. Removed file lookahead
- scheme as it was faulty.
-
- 2. Added Resend count to screen.
-
- 3. Send CPS now includes time to read block from disk.
-
- 26-SEP-90 1.30
-
- 1. Major rewrite of Send and Receive routines.
-
- 2. Corrected bug in Outchar routine.
-
- 13-OCT-90 NMODEM 1.31
-
- 1. A user report indicated problem with the method of handling the
- status window. Status window scheme now changed completely!
-
- 2. Improved handling of NMODEM.LOG and NMODEM.ERR files.
-
-
- 14-OCT-90 NMODEM 1.32
-
- 1. Eliminated a redundant clearscreen on startup.
-
- 11-22-90 Ver: 1.40
-
- 1. Changed the modem interface drastically.
-
- 2. Changed to TP 5.5 and used SYST55C2 from EAGLE Performance
- Software as well as TPCRT from Turbo Power Software!
-
- -----------------------------------------------------------
- NOTE: Problem reports are of little use unless it provides:
-
- A. DOS version.
-
- B. NMODEM.err copies.
-
- C. CPU, Modem and Comm program info.
-
- I get many messages "I can't get NMODEM to work! Whats wrong?".
- ----------------------------------------------------------------
-
- Please review Trouble.doc for possible help!
-
- 12-09-90 NMODEM 1.41
-
- 1. Added delay in init routine for slow modems/UARTS.
-
- 12-10-90 NMODEM 1.50
-
- 1. Major revision of modem interface. Hopefully will solve the

-
- 01-13-91 NMODEM 1.61
-
- 1. This version now has a new commandline switch for disabling
- the generation of the Nmodem.log file. Adding 'L' in the
