Subject: [c-nsp] Cisco 891F modem flow control
To: Cisco Network Service Providers <>

While I am testing modem on Cisco891F, when I try to get long output, such
as "show tech-support", many characters are dropped and cannot get correct
It seems flow control between internal modem and line of 891F is not
The part of config for line 3 (allocated to modem) is as below.

line 3
modem InOut
modem autoconfigure discovery
no activation-character
transport input all
transport output all
speed 115200
flowcontrol hardware

I used same config for Cisco1921 with WIC-1AM-V2, but there is no problem
on flow control.
I tried using several IOS from 15.3M to 15.7M, but every version had this
Is there any other command to enable flowcontrol on the Cisco891F?

Best Regards,
