Interface: serial

Hello everybody,

we are using smsd with about 12-16 modems. Currently we are searching for opportunities to host our sms server in Data Centre (DC) . Our trouble is that DC doesn't want to host server with modems. To solve this situation we consider the following setup:
a) sms server is located in DC without modems
b) modems are located at separate site
c) points a) and b) are connected via Internet
d) in point b) we can use device like http://www.virtualserialport.com/products/serial-over-ethernet/ , to make modems available for server at point a)

My questions are:
1) Whether such setup is reliable enough?
2) Whehter somebody used similar setup?
3) How good in quality serial communications over Internet are?

I think you can use such system:
points a) can use web server with some script which can recieve POST or GET request with message.
point b) with use some script send request to poin a) after recieving sms

You can use such system:

on point b) periodically run script which send requst to server in point a) and server in it answer return data with message texts. Script on point b) parses server answer, create files with sms data and write to smstool spool directory.

Yes.

You can take some script language, for example php, and write some script which will do all work like these ( very simple examples ):

Reading data from server:


Sned data to server:
