Dial in to AUX port

Hi,

I am trying to configure remote dial in access to a 3640 routers using a modem connected to the AUX port. The modem is a Hayes Optima. I have one 3640 that works correctly, one that dials in but I get garbage or nothing at all and another that won't dial in at all. The configs on all the AUX ports are the same and are as follows:

line aux 0

exec-timeout 5 0

login local

modem InOut

modem autoconfigure discovery

transport input telnet

stopbits 1

speed 115200

flowcontrol hardware

I'm using W2K hyperterm to connect.

The last router that won't dial in I can't establish a reverse telnet session to but the others I can. Also when I run the show line command the modem looks to be connected but even after rebooting the modem the status is the same.

Router#sho line 129

Tty Typ Tx/Rx A Modem Roty AccO AccI Uses Noise Overruns Int

* 129 AUX 115200/115200- inout - - - 0 0 0/0 -

Ready

Line 129, Location: "", Type: ""

Length: 24 lines, Width: 80 columns

Baud rate (TX/RX) is 115200/115200, no parity, 1 stopbits, 8 databits

Status: Ready, Active, No Exit Banner, CTS Raised, Modem Signals Polled

Capabilities: Hardware Flowcontrol In, Hardware Flowcontrol Out

Modem Callout, Modem RI is CD, Modem Discovery

Modem state: Ready

Group codes: 0

Modem hardware state: CTS* DSR* DTR RTS

TTY NUMBER 129

Parity Error = 0 Framing Error = 2 Receive Error = 2 Overrun = 0

Outcount = 0 totalout = 3706975 incount = 0 totalin = 2

Note also the DSR is set which on the routers that do connect is shows noDSR.

All ideas welcome.

Thanks

Re: Dial in to AUX port

You should be alteast able to reverse telnet to that modem from a router..

Try to do "clear line 129" and immediately try to reverse telnet to modem..

also if you get garbage while you dialin to 3640's AUX port modem..it could be because of speed mismatch..so disconnect the modem from the aux port, configure the command "speed 38400" under the aux port, plug the modem back..and try to dialin and see the results..
