- There are two potential problems:
-
- 1. The combination of terminal emulation software and processor
- speed on your end slow down text as it renders to the screen and
- scrolls.
- 2. The combination of BBS software and processor speed on the
- computer you are calling slow down text as it is pulled off the
- other machine's hard drive, possibly displayed on the other
- machine's console, and then sent over the modem to you.
-
- If your computer can't deal with text moving at that speed it will
- step in and use hardware flow control to slow down the incoming
- data. If the other machine can't generate text for the output
- buffer as fast as the modem on the other end wants it, the modem on
- the other end is going to take whatever is in its buffer, make a
- packet and send it along, slowing down the process somewhat.
-
- You can 1) Buy a faster computer, 2) Buy your SYSOP a faster
- computer, 3) show the author of your SYSOP's favorite software how
- to write faster code, or 4) get a better terminal emulation
- package.
-
- The modems have nothing to do with this.
