(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 :)
