Need to connect remotely to a device using cellular GPRS gateway.
Device supports RS-232 and USB. It boils done to two options:
1.- Serial Over TCP/IP (Serial to Ethernet - to GPRS, or Serial to GPRS)
2.- USB Over TCP/IP (USB to Ethernet - GPRS, or USB to GPRS)
Note that there are gateways that allow transparent communication from TCP network communications to serial port. Example: Serial to GPRS Gateway.
End goal is to have a virtual serial tty port. Tools like Socat in Linux allows this.
So application programs will think that the device is connected locally to the computer.
Which one should I use? People tell me definitely Serial over IP due to USB latencies issues...
P.S. I'm talking about Virtual Serial Port.
