(Sorry that Dave got fumed by all-caps writing -- I do know that
it is rather difficult even to get text written on GSM phones,
never mind mixed-case text.. This kind of email sending is a
mode which I too do every now and then -- although more often I
call my peers rather than email them, while I am commuting...)

I presume you do realize you are referring to ASYNCHRONOUS serial
port ? Not Synchronous ports ?

With Linux (all variants) it is easy to keep UART FIFOs full,
and thus to send the characters as back-to-back as that chip
allows.

Yeah, gateway footers are longer, than the maximum GSM message size :)
