Another point about these modems is they will auto-set the baud rate *and* *parity* from the first "AT" command they get. Once they think the're getting even parity they will ignore any odd bytes. Check that dial-in modems get setup from a terminal with parity off, and dial-out ones have a "P_NONE" (or similar) statement in the uucp chat script. --Andy Ingle
