Remote serial ports?

Hi all,

I have an application in which it would be useful to have access to remote serial ports as if they where local ports.

Machine A has several serial ports on it connected to various special types of devices in a locked machine room.

Developers on workstation B wants to execute an application that communicates with the special devices, but can only do so via /dev/ttySXX. The developer however (for various reasons) cannot directly log into Machine A.

Is there some software that would allow "remote forwarding" of serial ports? I.e. a driver that emulates a serial port on machine B and forwards the read/write/ioctl operations to machine A? Does this exist? Is it possible to implement if it doesn't? Am I overlooking something obvious?

Thank you in advance,

Jens Petersohn

Please see the posting on l-k today "[NEW DRIVER] New user space serial port" which does just what you want. Just-in-time kernel development has arrived.

Cheers, Andreas
