serial port server

[Jaroslav Lukesh]

Dobrý den,

potřeboval bych přesměrovat data ze sériového portu linuxu do počítače s 
windoze.

Představuji si to tak, že by na linuxu jel nějaký sertial port server, 
který by data ze sériového portu převáděl na některý TCP/UDP port.

No a na windozech by byl ovladač, který by data z TCP portu onoho stroje 
vyzobával a tvářil se přitom jako některý COM port.

Našel jsem k této problematice jedinou postarší stránku:
http://www.linux.ie/articles/industry/bluetree.php
leč odkyz v ní
ftp://ftp.bluetree.ie/pub/portserver/
je nikam.

Kdybyste někdo tušil, kde by se daly nalézt takovéto utilitky, byl bych 
mnoho vděčen.

Dík moc,

JL.

PS. protože ta stránka je šíleně dlouhá, vybírám z ní relevnatní část:

 > I'm intriqued by the serial port server that you run on an old 486, 
what exactly is involved (it just sounds rather unusual to me)?

Grab an old 486SX25 with 4MB of RAM, 3 ISA slots and 100MB of disk.
Install a Stallion EasyIO 8-port ISA serial card. Install an old ISA 
ethernet card.

Install my portserver software (available from our FTP site). I've now 
got 10 serial ports accessible from anywhere in our network.

Next, I modify our in-house Windows comms library to take port names 
such as "*rterm/hydra.bluetree.ie/external1" as well as old-fashioned 
names such as "COM1:".

Now any applications using that library can transparently communicate 
through those remote ports.

We develop software that downloads data from data logging devices. 
During test and development, we need to be able to communicate with 
loggers from different manufacturers, running different protocols and 
firmware revisions. Lugging loggers, power supplies and cables from one 
developer's desk to another was a real pain. Instead, they all go in one 
corner of one office and anyone can communicate with them.
