 DISCUSSION OF 7/8 DATA BITS

 Most text data can be represented by 7 bits, while programs and
 archives require 8 bits.  When configuring an RS-232 link, you must
 get both ends to agree on how many bits will be used to represent
 the data.  In most cases, this boils down to setting your
 communication program to match the service you are calling.

 Most bulletin boards use 8 bits, while many packet switching
 networks (such as TYMNET), VAX systems, and UNIX systems use 7 bits.

 Telix and most communications programs (but not all!) are smart enough
 to switch from 7 to 8 bits when set for 7 bits but using an
 upload/download protocol that requires 8 bits.

 If you are calling a new service and don't know which to use, use
 8 data bits and no parity.  If you see strange characters appeaing
 on the screen when you expect text, switch to 7 data bits and even
 parity.
