- We have a few Annex terminal servers. Some say Encore on the front, the
- others say Xylogics. We would like to connect a rack of Telebit T3000s
- to the annex and use RTS/CTS (hardware) flow control so we can run the
- DTE speed flat out. The Annex hardware manual indicates that the only
- control signal from the modem to the Annex is DCD, and that the only
- signal from the annex to the modem is RTS. The Annex software admin
- guide implies that you can indeed do hardware flow control by setting
- the port parameters as follows:
-
- set port control_lines flow_control
- set port input_flow_control eia
- set port output_flow_control eia
-
- My question is, how in the world can one really do hardware flow control
- without having RTS and CTS available? Has anyone successfully connected
- a Telebit T3000 to an Annex terminal server? If so I would really like
- to hear how you did it. Please reply directly to me via e-mail.
-
- Thanks.
