I am using the pilot version of the ads board,and  indeed run the
init8260 example from mot web site.How do you connect the pins?
According to ads manual,pin 2 from connector is tx,pin 3 is rx,
,and i also connect pin 4( DTR connect with SCC1 CD on PC14) with
pin 6(DSR).The output volatege is 0-5V.but the logic is 232.
I think it should be i had not  connectted the pins  correctly?
At the time of writing,when i reading the ads manual,i found CTS(pin 8) connect to SCC1's RTS on PD29.But the Init program did not program
this pin?How about eng version's connection?Should i program this pin?
