Forcing serial handshaking

Hi,
I'm having trouble drawing up a schematic for an FT232BM serial
converter chip, and an AVR. I assume the normal rules of serial apply
to it. Does this mean that I can connect CTS to RTS together and DTR
DSR DCD all together too? This apepars tho be the case in
http://www.airborn.com.au/pcb02/ex20514c.gif (at the top left). Should
this work, or is there something else I should do?


many thanks

The PC application operating the comport determines the use of the
handshake lines. They are not required if the application doesn't
implement them.
But yes, if they are required, then you can short them, as if it was
a normal comport.

Hi,

I use my PC serial port for any number of things. All I usually use is
XMIT, RECV, and Ground. Occasionaly, I use one of the other output
lines for a power source. The input handshake lines are only used if
the PC application specifically calls for their use, but jumpering them
back that way will not hurt either.
