Works a little further ...

root@calamity [~]# /usr/sbin/slmodemd -b
SmartLink Soft Modem: version 2.9.9 Apr  8 2005 12:53:44
symbolic link `/dev/ttySL0' -> `/dev/ttyp5' created.
modem `sound1' created. TTY is `/dev/ttyp5'
Use `/dev/ttySL0' as modem device, Ctrl+C for termination.

root@calamity [~]# cu -l ttySL0
Connected.
atz
OK
atdt3300
                      <--- HANG HERE

At that time, slmodemd eats all the CPU.

  PID USERNAME PRI NICE   SIZE   RES STATE      TIME   WCPU    CPU COMMAND

It seems to be stuck in a read() loop from netbsd_device_read() :

root@calamity [~]# gdb /usr/sbin/slmodemd 164

Will try to figure what's going wrong.

Thanks.
