Virtual com/serial port

Hi,

I have two asus routers (wl500g) with linux installed on it. The
routers have both wlan on board. Both routers can communicate with
sockets. On one router is a program that can write to a serial port
e.g. /dev/ttyS0 on the other router is a program that can read from a
serial port also /dev/ttyS0. I have found a program (VSPDL) from
http://www.tibbo.com/vspdl.php which creates a virtual com/serial port
and communicates over an existing tcp connection.

VSPDL consists of a kernel module (which is open source) and a
deamon/process (which is closed source). VSPDL works perfect on x86.
The deamon is x86 only, because only the binary is delivered. The asus
wl500g has a MIPS processor on board. This means that VSPDL won't run
on the Asus. I have mailed the guys from tibbo and they will not
release the source of the deamon or the binary for MIPS.

I have surfed on the internet to find another virtual serial port
program (open source or closed source with binaries for the MIPS) but
found nothing.

Is there someone who knows a program that can create a virtual serial
port. Maybe there is someone with some other sollution to the problem.
I know i can rewrite my programs which communicate with serial ports to
programs that communicate with sockets. But this is not really an
option.

Thanks in advance.

Greetings Bjorn.

Columbia U had a virtual com port implementation as part of the Kermit
suite. It was open source. It consisted of a daemon and a client; I
don't recall any more. I know the client ran on both linux and windows
boxen. The daemon was linux only.... It was not a part of the normal
kermit tarball; instead you had to download it off their ftp site.

I don't recall the name or any particulars. I know I used it and it
worked.....

Thank you for your help, but does anybody know how this program part of
the Kermit suite is called a searched de website but i could not find
it.
