Hi scsijon Thanx for your response (the only one I have gotten). The problem is that even switching the modem off won't clear rts. at&c1 will enable rts handshaking and works fine on other operating systems. Flow control is working when the user is connected, it is just that rts drops when a user disconnects and stays low. I have even gone so far as to store a pofile in the modem and read it back when the user disconnects using a chat sript. rts must be being held low by the the OS. Even a switching off the modem disconnecting is then reconnecting it doesn't fix the problem. The only fix is to reboot Linux. Any other ideas? Thanx Chris
chris, you may need to download a code to tell your modem not to leave RTS low after signal is cleared, your manual should give the code.
Also are you using Modem port /dev/cuaxx's or direct serial /dev/ttySxx's? As the second will hold the port open as long as the modem is connected unless told to close cause it can see a device the other end.
regards scsijon

On my server, when user who has dialed inot my system (using ppp) hangs up, the RTS on the modem stays low. The problem with this is that the modem can
---------- then
answer the next incoming call but cannot receive data, ie cannot recieve any login.
If I use minicom it can raise rts and use the modem.
The only way I have found to raise rts is to reboot the server.
is there anyway I can force the port to raise rts when the carrier is dropped via a script or something?
