By default linux uses RTS/CTS hardware flow control, so a modem working this way will be slow and unreliable. I have one modem that needs an AT\S3 command to fix this; at that point in the AT command set this is very manufacturor-specific. I hope you have doco for your modem. You may well need to read up on the commands it understands. Of course, in a chat script the \S3 needs to be escaped - twice, since the way I set it up it goes through bash twice: (This is the entire pppd setup for this modem, except the dial command, and user name, which you don't need to know.) /dev/tts/3 is what devfs calls what used to be /dev/ttyS3. /dev/tts/3 115200 lock noipdefault debug asyncmap 0 crtscts ipcp-accept-remote ipcp-accept-local defaultroute usepeerdns connect '/usr/sbin/chat -v ABORT BUSY \ "" "AT&FX4&C1&D2&S2\\\\Q3%C0&H0S7=60" \ "CONNECT" "" "" ""' > > Do you have any other ideas? > > I appreciate your help and advise to date.

The modem may need some initialization before you tell it to dial...nine needs an init string like so: "" "AT&FM0B1T&B1&H1&R2&K1&M4&S1S13=1S7=60" (that is from my pppd chat script, that's why it has a null expect string first: "". I have a similar init string configured into my windows mail app, but the pppd chat script is more accessible, so I showed you that. Try at least AT&F to reset the thing to its factory defaults, you may well have hurt it messing around with echo. It is in the original spec for the Hayes SmartModem 2400 that mIxeD cAse in modem commands may cause the modem to behave in an unspecified manner, and most modems I have experience with do hANg when commanded in this manner, and may need to be reset. Commands may be in UPPER or lower case, but Please don't mix case. Repeated AT AT AT or ATH ATH may work instead of a hardware reset. I like cu, it is a very crude simple easy to use terminal emulator, but you need something like a terminal emulator, you need to both write to and read from the modem device with one process. well, chat -v will do in a pinch: /usr/sbin/chat -v "" "AT&F" "OK" "ATH" </dev/ttyS0 >devttyS0 look in syslog for any output from chat, you should see send (AT&F^M) expect (OK) AT&F^M OK -- got it Now let's see if the modem still works...
