[time-nuts] Serial port server .. any interest in a write up onusing ?

[Azelio Boriani]

There are Lantronix CoBox, XPort too and the TIBBO. Something like
ebay 370532038785,
290714846432 for those of you in the States or 270711839584 for the Europe.
They are one_serial_port-to-ethernet adapter based on the telnet protocol
but Lantronix has a virtual COM port driver to translate the ethernet
attached serial port into a normal COM port on your PC.
