- The DECserver 200 M/C series have a bug with the ACCESS DYNAMIC setting. It
- sometimes causes the problems you describe. The fix? use it as Access Local
- only, and dial out somewhere else.

- DS 200's should be set to flow control: XON - they still honor CTS.
-
- DSR logout should not be enabled. If you set privs on your session, and do a
- help set port dsrlogout, you will see the following:
-
- This port characteristic lets the server automatically log out a non-modem
- controlled port when the device is powered off. this characteristic may be
- used only with MODEM CONTROL disabled. When MODEM CONTROL is enabled, this
- function is performed as part of the normal modem interaction.
-
- Dump the RING, also, you shouldn't need it, and it will cause problems too.
-
- You should also make sure that the server is running at least V3.0 of the
- DS200 software also.
-
- Below is my DS200 settings, works fine with a Telebit Qblazer modem set with
- CSR flow control, no result codes, etc. I will post my Qblazer settings
- below also...
