Re: reading from Serial Port (com port 1 to 10)
Some of us have written jPos serial handlers for our specific needs
and I don't know about everyone else's experience, but I finally gave
up trying to use serial ports in servers and PCs, as there are good
serial boards and bad serial boards and their reliability is not
consistent. Besides, for reliability, dependability and other obvious
reasons you want to decouple yourself from the PC.
* If you're serving incoming POS, use something like a Hypercom NAC
device. You won't have to worry about modems, serial ports or any of
* If you're connecting serial devices directly, use an external device
server like Moxa device server series or Digi PortServer.
In both cases your software will just talk straight TCP/IP and the
device does all the serial management. It also works good for
redundancy since it's networked, if you have standy boxes, getting the
serial devices to see your other cluster box(es) is a snap!
IMHO these days it'd actually be a crime to plug a serial device
directly on the server(s), but I could be wrong. haha
