forcing modem speed

How can I force the modem speed on a NM-8AM-V2 module to V22 (1200 bps).

Re: forcing modem speed

Simon,

The AT commands for the NM-AM-V2 modems are documented here:

http://www.cisco.com/application/pdf/en/us/guest/products/ps275/c1049/ccmigration_09186a00801e6fc4.pdf

The specific command to configure them for V.22 is

"AT+MS=V22". You may also want to mix in commands to

disable error control (+ES=1,1,1), reset to factory

defaults (&F) and autoanswer (S0=1).

The recommended method for configuring a modem is to

use autoconfigure. http://www.cisco.com/en/US/tech/tk801/tk36/technologies_tech_note09186a008009491b.shtml#configmodems

Putting it all together, you might use something

like this:

term monitor

debug confmodem

config t

modemcap edit V22 misc &FS0=1+MS=V22;+ES=1,1,1

line 33

modem autoconfigure type V22

Cheers,

Aaron
