21-JUN-90 Ver: 1.00e
1. Optimized the send and receive routines a bit more.
2. Removed comm port test as it failed with 16550 UART due to
differences.
04-JUL-90 Ver: 1.00f
1. Worked on cancel sequences.
07-AUG-90 Ver: 1.00g
1. Faster send.
2. Improved carrier detect.
31-AUG-90 Ver: 1.00h
1. A bit faster than before.
11-15-90 WXMODEM 1.00j
1. Source for 1.00i went when my HD crashed, so this is 1.00j based
on improvements to 1.00h code.
2. Changed CRC scheme for faster turn around.
3. Corrected the status of some variables to improve reliability.
4. Optimized the send loop a bit more to improve speed.
12-08-90 1.00k
1. Increased time to allow for "wxmodem" handshake!
12-26-90 1.00l
1. Revamped modem interface.
18 Feb 1991
1. Added improved interrupt "kicking" seems to increase thruput
a bit.
03-13-91 WXMODEM 1.01n
1. Corrected stupid code by me.
03-14-91 WXMODEM 1.00p
1. Skipped 1.00o.
2. Improved speed once again.
03-14-91 WXMODEM 1.00q
1. Adjusted receive buffer interface.
04-15-91 WXMODEM 1.00R
1. A tad bit faster again!
04-19-91 WXMODEM 1.00s
1. Faster send!
07-20-91 1.00t
1. Average CPS now displayed in status window.
- For accuracy real (decimal) math must be used so the .EXE
is about 2k bigger than before.
2. Changed some variables to typed constants to establish startup
value.
08-14-91 WXMODEM 1.00u
1. Adjusted the CRC system.
2. After the first block is sent the approximate transfer time now
is shown on the send screen. NOTE: This calc based on numbers
related to 225 cps at 2400 bps. It should be fairly accurate on
most machines. Since the program has no way to know the baud
rate, I have sampled the CPS of the first block sent and based
on a rather large window then guessed the prime rate.
