- Hi, Todd...
-
- Well, i can just speak about some problems connecting to plain modems in
- general with the supra, that is modems with no error-correction or compression.
- Because these modems can`t do it, they receive after a connection the bytes
- with which the sending modem (in our case the supra) tries to make a
- MNP or V.42(bis) connection, but these bytes will then be normally received
- by the receiving modem and so directly to the BBS or whatever you call.
- Now it depends heavily on how the BBS reacts on such "garbage" during
- login. If its a good one, it`ll just leave out these characters or wait a
- few seconds after connect to ensure not getting those "connect" bytes.
-
- I had big problems when calling my university, as they still have only plainb
- modems without any MNP or V.42(bis) and i also got thrown out in 50% of the
- times.
-
- But there is an easy solution to this:
-
- You just have to change the supra from auto-reliable to normal connect, where
- the Supra doesn`t try to make any MNP or V.42(bis) connection and therefor
- doesn`t send these garbage characters.
-
- The command for this is: AT\N0
-
- I would recommend to include it in a second dial-startup string
- (like AT\N0D) and use this dial-startup string for every plain modem you are
- calling.
-
- Hope this will help you.
-
- Read ya, Phil
