I want to send and receive shot text (and if possible, binary) data
between two PCs.
The link between PCs will be low-cost off the shelf mobile phones (may
be from second hand stores).
[PC-A][Mobile Phone-A] [Mobile Phone-B] [PC-
In this configuration "[PC-A][Mobile Phone-A]" pair will be
stationary and the "[Mobile Phone-B] [PC-B]" pair will be mobile
in a car (ideally a mobile robot).
I do not have experience with the mobile phone interface and I would
like to ask expert technical advise on the following questions;
[*] Which (low-cost) brand/model phones have RS232 interface to
connect it to PC?
[*] Is it possible to use modem's AT command (or something similar)
to dial remote phone and send text (or binary message) directly, like
PC to PC modem connection?
[*] Or does the telephone exchange should store the message and
forward ot to destination when everit want?
Thank you for your help,
