Default serial console settings for Linksys Switch SRW224G4 (can be changed): Bits per second: 38400 Data bits: 8 Parity: None Stop bits: 1 Flow Control: None Works great in PuTTy , just set connection type to 'Serial' and set speed manually (38400). You'll need a "console" cable for this, but its not a rollover - it's a DB9F to DB9F straight through.
