It's a kernel-mode serial driver that talks to an Ethernet-attached device server. We were talking about an application in user-space creating a virtual serial port weren't we? If the question was can one write a kernel-mode serial driver for Unix systems (e.g. Linux), then the answer is obviously "yes". There's no doubt you can implement a serial device if you write a serial driver kernel module: there are dozens of such drivers. Most of them talk to UARTs on a local ISA or PCI bus boards. There are also quite a few that talk to USB-attached hardware, and there are probably at least a half-dozen companies that sell Ethernet-attached serial hardware with Linux drivers. (I maintained an Ethernet-attached serial driver for one of those vendors for many years). -- Grant -- http://mail.python.org/mailman/listinfo/python-list
