Can you let me know if the WiModem supports window size negotiation / RFC 1073?

Here are the client / server telnet protocol flows for a working session (telnet client = Ubuntu) in case it helps.
client:
> telnet
>> Do Suppress Go Ahead
>> Will Terminal Type
>> Will Negotiate About Window Size
>> Will Terminal Speed
>> Will Remote Flow Control
>> Will Linemode
>> Will New Environment Option
>> Do Status
server:
> telnet
>> Will Suppress Go Ahead
>> Will Echo
>> Do Negotiate About Window Size
client:
> telnet
>> Do Echo
>> Suboption Negotiate About Window Size
>> Suboption End
server:
>telnet
>> Don't Terminal Speed
>> Don't Remote Flow Control
>> Don't Linemode
>> Don't New Environment Option
>> Won't Status
