Hi,
Does anyone have experience with Falcom A2D, Falcom Tango, Siemens TC35T
GSM Modems?
Any Advice on reliability, usage etc?

I am looking at using them in vehicle based SMS messaging and ftp data
transfers from windows 98.

I am based in the UK.

Thanks,
Jon.

I implemented a system utilizing a Falcom GSM modem in 1998.

It was a painful experience.

Hayes compatibilty was poor, and modem had several interesting quirks
which required significant engineering effort to work around.

In addition, it took a month to receive the modem due to the entire
company going on holiday at the same time.

The Wavecom Fastrack seems to be highly recommended these days.
Especially as Siemens seems to have outsourced their firmware
development.

There's a recent recommendation for it on alt.cellular.data,
subject "Siemens M20 GSM modem".

I agree. Our experience with it has been very good.

The TC35T firmware was supposedly rewritten from scratch, which was a
very bad move. As a result, it got bugs which the M20T had not
previously experienced... We tried the TC35T but rejected it in favour
of the Wavecom Fastrack.
