hi,

i'm trying to use my elsa microlink tqv (33k) modem with mgetty under
debian linux 2.1. actually i had it working on another machine before
under SuSe linux 4.1.

after mgetty sends ATI to the modem, i just get Warning: got alarm signal!
mdm_read_byte: read returned -1: Interrupted system call. i tried to find
something in the documentation, mailing list archive and faq, but was not
sure what i should look for, because i don't understand the error message.
i hope somebody can help me or at least tell me where to find information.

here is some information about my system (i hope it is sufficient).

the configuration of my system is:
processor 80486/33
os: debian linux 2.1 
kernel version: 2.0.36
serial ports: 
  tty00 at 0x03f8 (irq = 4) is a 16450
  tty01 at 0x02f8 (irq = 3) is a 16450
  tty02 at 0x03e8 (irq = 4) is a 16450A 
  tty03 at 0x02e8 (irq = 3) is a 16550A
  (the modem is connected to ttyS2)
modem: elsa microlink 33.6tqv
mgetty: binary package from debian 2.1 (appears to be version 1.1.18)

the only things that are in mgetty.conf are
debug 6 
fax-id xxxxxxxxx (where xxxxxxx is my phone number)
speed 38400 

here's the logfile
