The Wang 2200 Flow Control and Reverse Flow Control options support a
special two-level in-band flow control mechanism characteristic of the Wang
2200 computer system. The Wang 2200 terminal may have a printer attached;
when it does, separate XON and XOFF reverse flow control characters are
generated by the CRT and the attached printer. These in turn are propagated
separately by the 2031
Turbo
multiplexer as flow control characters to the host
end. The CRT issues an XOFF of FA hexadecimal and an XON of F8, while the
printer uses an XOFF of FB and an XON of F9.
To support this mechanism, the
WANG
option must be selected for the Reverse
Flow Control option at the terminal end; at the host end, select the
WANG
option for Flow Control,
NONE
for Reverse Flow Control, and
YES
for the Flow
Control Translation parameter.
