HANDSHAKE Hn

The Handshake control command enables software control of the handshake

lines, independent of any other I/O operations. When the Digital232 receives an Hn
command, the respective handshake line is pulsed for approximately 50 microseconds.
It returns to its steady-state condition after pulsing. The Invert command may be
used to change the active state of any of the handshake lines.
