Gnokii hangs on ttyUSB0 at an ioctl

[Ligesh]

 Hi,

  I am facing a peculiar problem with gnokii. It works beautifully for a couple 
of times, then chokes on this particular system call.

  ioctl(4, SNDCTL_TMR_TIMEBASE or TCGETS, {B0 -opost -isig -icanon -echo ...}) 
= 0
  ioctl(4, SNDCTL_TMR_STOP or TCSETSW <unfinished ...>


I am using usbserial cable, and if I unplug the cable and insert it back, 
gnokii starts working, but only for a couple of times, after which it gets 
stuck at the same point. Could anyone tell me any workaround for this. It must 
be that there is some way to 'flush' the serial cable other than reinserting it.

Thanks in advance.
