    You can't change it to an arbitrary value.  It should support:



    1200

    2400

    4800

    9600

    19200

    38400

    57600

    115200

  • I will assume that we are talking about a TTY line on the router here.  What do you have connected to it?

    Generally speaking, we're talking about serial baud rate, which is largely dependent on what's on the other side.   Some devices (including the outbound side from Cisco) will max out at 38400.  Newer ones will max out at 115200 for async connections.

    Depending on the interface and router and IOS, you may get help with ?....

            Speed (bits per second)
      300
      1200
      2400
      4800
      9600
      14400
      19200
      28800
      32000
      38400
      56000
      57600
      64000
      72000
      115200
      128000
     
    Those are Cisco's supported async line speeds.  If you are connecting to a modem, then check out your modems capabilities as well.

    HTH,

    Scott
