Ultra 5 Serial connection

Hi,

I am having a few problems connecting an Ultra 5 to my laptop via serial cable.

I have looked at the following instructions:

http://www.sunhelp.org/unix-serial-port-resources/serial-pinouts/#u10.link

and have reviewed the following post:

http://forum.sun.com/jive/thread.jspa?forumID=246&threadID=93916

I have made a db9-db9 cable with cross over between pins 2-3 and pin 7 straight through as suggested.

I have'nt updated the eeprom to point to ttya (I'm sure this should'nt make a difference as long as the keyboard is'nt plugged in - which it is not)

Is there anyone out there who has got this to work with an ultra5 - am I missing something obvious?

Any help gratefully received.

Hello,

I have made a db9-db9 cable with cross over between pins 2-3 and pin 7 straight through as suggested.

The console port is serial A (DB25), the DB9 connector is serial B.

If no keyboard is attached, input/output is taken from/directed to the console port(serial A) ttya.

Hello.

>> I have made a db9-db9 cable with cross over between pins 2-3 and pin 7 straight through as suggested.

This is true for db25-db25.

For db9 this is totally wrong!

db9 - db9:

2-3 must be crossed over, pin 5 (not 7) must be straight through

db25 - db9 (this is what you need):

2,3 must be straight through (not crossed)

pin 5 of db9 must be connected to pin 7 of db25

(This is the minimum configuration; you may also connect other pins like DTR-DSR; CTS-RTS; ...)
