Data Options and Profiles
Trans.flow (Transmit Flow Control)
Option Values: xon/xoff, eia, off
Applicable Data Protocols: X.25, Mode 3, all V.120 modes, and Mode 2*
This option determines which method is used to control the flow of data from
your data terminal to the ADM.
When you select xon/xoff, the ADM sends your data terminal an xoff character
(with current parity) when it is not ready to receive data. The ADM sends an xon
character (with current parity) to your data terminal when it is ready to receive
data. This setting is appropriate for most users.
Select eia, if you want the ADM to use the Clear-to-Send (CTS) lead to indicate
whether it is ready to receive data from your data terminal. When it is not ready
to receive data from your terminal, the ADM turns off CTS. When it is ready to
receive data, it turns on CTS.
Once the ADM turns off CTS, flow from the data terminal to the ADM stops
immediately. Any information sent after CTS drops is lost.
* For a Mode 2 call, this option is in effect only at the high-speed endpoint (see Match.speed).
