Well, in terms of wired serial vs wired TCP/IP I was more thinking
about the scanner having to deal with the connection states and
protocols for initiating / maintaining socket connections.

I can definately see how a wireless bar-code scanner would be a great
advantage. I hadn't thought of a need for a solution like that. Also
forgot about the maximum length ofr serial tranmission. Thanks for the
information!

At this point of the development process, I need to test how to connect/disconnect the modem and how well TCP/IP can handle those situations where the link goes down due to GSM/GPRS network troubles; the modem behaves just like a plain old serial modem once it's connected, but the connection is actually quite unreliable, and when it drops that isn't always reported immediately, i.e. the connection can drop and the controlling software will only know this after some seconds. ... I need to know how TCP/IP can handle this, and if a TCP/IP client will have exact knowledge of how many data actually reached the remote server; besides, I also need to test the AT command set the modem uses. ...
