Re: how fast are Mod 170 comm ports

[Matthias Oertli <oertlim@xxxxxxxxxxxxxxxx>]

Hi,
The AS/400 RS232/V24 ports max out at 19.2kbps. No modem, no matter
how fast will be able to talk to your 400 at a faster bitrate than
that. For higher speeds you need to use a different interface (X.21 or
somesuch.)

Regards,
Matthias
