modem sharing

[Charles Galpin <cgalpin lighthouse-software com>]

HAs anyone read the Linux modem
sharing howto? (/usr/doc/HOWTO/mini/Windows-Modem-Sharing)

The basic concept is to be able to use a modem on a Linux both from other linux
boxes, or windows boxes with COM port redirector socftware.

I have attempted to setup a modem server using both the perl script provided,
and mserver, but both give me errors.

I CAN do 
echo atdt1234567 > /dev/ttyS1

and the modem will dial out, BUT this ( the heart of the perl script) fails

# cu -s 115200 -l /dev/ttyS1
cu: open (/dev/ttyS1): Permission denied
cu: /dev/ttyS1: Line in use

similary with mserver and say port 5800, I get an error saying it can't bind
the server socket (address in use). 

So I tried telnetting to that port
#telnet localhost 5800
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
DEVICE INACCESSIBLE
Connection closed by foreign host.

Doesn't this mean it's not in use?

any ideas boys and girls?

   Do not committ homicide.  The modems in Jail are all
   Winmodems and work at only 300 baud.
