I have a really irritating problem that just popped up out of the blue. I
have been running my Lionux system now for close to a year, and have survived
various little glitches that have come out of the woodwork.
This one stumps me.
Until now, my modem, slip, ppd, etc have been working perfectly. Today, I
tried to establish a slip connection to my provider, and nothing but errors
occured. Same with ppp. Looking in the syslog, I found this:
Jul 29 13:11:41 freebeer pppd: tcgetattr: I/O error
Jul 29 13:11:53 freebeer dip: DIP: tty: get_state: I/O error
I cannot make any kind of connection out of here via the modem... I have tried
minicom, slip, pp and nothing works. Now, it gets interesting. When i exit
linux, and start up Trumpet Winsock, I find that the modem is completely
unresponsive. I have to reset the machine, or power it off to restore proper
serial port operation under dos/win.
Aside from adding a second hard drive (modifying fstab accordingly) and
exchanging a Logitech busmouse for a MS serial mouse, I haven't changed a
thing in my Linux setup.
The serial ports are located on a Promise 2300 Plus EIDE card, and are both
16550's (even now, Linux still reports them correctly).
Any advice would be appreciated.
