[c-nsp] 2911 Terminal Server 8bits character problem

[Rano Karno]

Hi Cisco-ers,
i have a setup to configure cisco 2911 as a terminal server with this inventory:- CISCO2911/K9- HWIC-16A- IOS : c2900-universalk9-mz.SPA.150-1.M3.bin
the topology :Terminal host ==<octopus cable>==2911 router==<utp to switch>==Server
the issue is whenever server make a session to terminal host and sending "FF" hexa, it seem the router did not transmit it to terminal host, thus make the system hang.
it seem whenever router received "1111 1111" bits the problem occurs.i have tried to setup "data-character-bit 8" and "special-character-bits 8 " but still cannot received full oxFF character.
appreciate if anyone can help for this.
regards,Rano
