- PEAK PERFORMANCE for US Robotics 14.4K
-
- Enclosed is a small utility I wrote for obtaining what I consider the
- best settings for the 14K. I have used these settings with Telix,
- including the most recent version, and have had excellent results.
-
- The CPS is not only dependant on your hardware, but also the BBS you
- are calling and the condition of the line you access from Bell. On
- average, using Ymodem-g protocol, I achieve speeds of about 1700 -
- 1750, depending on the size of the transfer. I have on occassion hit
- the 1800 mark which I account for the tolerances of the components of
- the 14.4 as by theory, it should not exceed 1750 CPS with 8 bit words.
- Zmodem transfers are usually around 1500 - 1600 CPS. Once again
- depending on all factors.
-
- The 14.k is an excellent modem for correcting for poor line
- conditions, and as a result, I have set 32 bit CRC for Zmodem off in
- the attempt to get the fastest file transfers. After you run this
- program, the suggested settings for your 14.4K switches and terminal
- software are displayed on the screen. One last word of warning, this
- program automatically writes to the NRAM in your modem. I have not
- included the option to abort, because if you are looking for the
- fastest settings possible, you're either getting them right now, or
- you will be after you run the program.
