voice calls to faxmodem (slow recovery)

[Tim Tsai <tim@futuresouth.com>]

  I have v4.0pl1 running and I am receing a normal fax just fine.  The
problem is that if somebody calls our fax number by mistake and hangs
up, it takes 3 minutes for HylaFAX to figure out that somebody has hung
up.  Is there any parameter that I can set to help this?  The
modems I have are USR Sportster Vi 14.4's and are configured for
class2.0 interface.

  A session trace follows.  We'd appreciate any information you may
have.

  Thanks,

  Tim
