Novaterm 9.6 User's Guide
If you have a 14.4k or 28.8kbps modem, you will notice that there are
no settings for those speeds. This is because high speed modems
support data compression and error correction. 14.4kbps or 28.8kbps
indicates the rate of compressed, error-corrected data transfer. The
actual rate of "real" data (before and after compression) will be at
least 14.4k/28.8k, but usually higher. That's what your modem box
meant when it advertised something like "speeds up to 57.6k
possible!" Therefore, these modems allow you to set your terminal
program to a speed higher than the modem's rated speed, in order to
take advantage of compression and error correction.
The standard way to do this is to always set Novaterm to the highest
possible baud rate, and turn on hardware flow control. Hardware flow
control allows Novaterm and the modem to dynamically manage the
flow of data depending on how well the compression is performing
(which depends on the type of data being transferred). (see 4.6.2,
Flow control).
4.1.3 Word/parity
Most on-line services operate at 8 bit word length and no parity.
Therefore, you should set this option to read 8N1. Some on-line
services may require you to use "even" or "odd" parity instead, in
which case this setting should be 7E1 or 7O1. However, you should
specify the Word/parity setting in the dial entry for each on-line
service in your dialing directory, since the setting can be different
from one service to the next. It's best to leave the setting on the
Configuration menu set to 8N1, and just let it change depending on the
service you dial.
4.2 40/80-column settings
4.2.1 80-column driver
This option specifies the driver to use for 80-column mode. In other
words, this option determines which set of programming code to use
to display the 80-column screen. The drivers currently available are:
default: The standard, unassisted 80-column driver that uses the
C64's high-resolution bitmapped screen.
fast-REU: Uses a RAM Expansion Unit (1700/1750/1764) to
implement a fast scroll on the C64's hi-res screen. You must use the
REU memory driver in conjunction with this driver (see 1.1.8,
Specifying the memory device).
