I am using a USR 56K Sportster modem with my Duo
2300c. I had to make a custom cable as described on
the 3Com support site. Here is the address to the
page:
http://www.usr.com/support/docs-template.asp?prod=s-mac
There is a link to hardware handshaking cable there.
What are you trying to connect to using your serial
port on the 280c? Maybe more information about your
setup would get more responses. Good Luck!
