Title: Using International Hex Chars 91h and 93h with CS/200 Flow Control
Date: 2/21/91

The hexadecimal characters 91h (^Q) and 93h (^S) are commonly used in
international character sets.

On the CS/200, when DAtaBits=8 and FlowControl to and from is set to
XON, XOFF, only the low-order 7 bits are checked against XON, XOFF
characters (octal 23 and octal 223 are interpreted as ^S).  Therefore, 91h
and 93h are interpreted as XON, XOFF characters.

The solution is to include "DoNotFold" in the parity parameters.  The
DoNotFold option is used in conjunction with "None, Even or Odd" parity.
This option allows the use of single eight-bit ASCII characters for control
characters such as XON and XOFF.

If the DoNotFold option is selected, the DAtaBits parameter must be set
to 8.
