[aprssig] APRS Email -> Cell phone Text message problem

Ha, Success!  It can use some tweeking on both sides (the D7 and the gateway), but the message was received, and the phone did NOT reboot.

>From the D7 I sent a message with "message subject" as the subject, and one line of text "Message text", followed by a message with the /EX terminator.  What she got was:

"Message received Message
text**************************************************** This message
was sent using a remote device which *** *** has limited capacity. 
When replying use plain *** *** text and keep the message as short as
possible. *************************"

So, "Message text" is indeed in there, but the subject is deleted since apparently that has no equivalent in a SMS text message.  The "Message received" part is from the D7 sending an automatic acknowledgment message (which I probably should turn off for this), and then there's all the extra fluff of the message length warning.

I wonder if it would be possible to add a command to the gateway (ST instead of SP, perhaps) for sending to Text message recipients, that would leave out the extra warning text (since they can't send much back either)?  Or maybe end with /ET instead of /EX, if the gateway doesn't want to remember how the message started?

Would the "Winlink system administrator" be a good contact person for this suggestion?

Also, I tried sending a short message back to my D7 from a regular email program, and it also worked, but again the message length problem was very limiting.  I can see the whole string on my Xastir gateway, but when it gets to the radio, I see the subject line and the sender's email address, but the text is truncated.  I thought the messages were sent in pieces, so that you would see the whole thing...  Did I not retrieve it correctly?  (sent "r1" to the gateway from the D7).  Or, is the D7 not configured right?

Thanks!

Hi Brian,

Ah, this one looks promising.  Plain text, multiple lines (Thank you!), and I get to set both the subject and text contents.  The only issue might be the message length, due to the long hunk of text warning you about the limited reply capability.  (Ironic, no?).

I've got an email out to my daughter to warn her it's coming...  I'll let you know.

See 
if you have the problem sending messages via the APRS-Winlink Gateway. I like 
the fact that you can assign an alias for a long email in APRSLink which 
certainly shortens the keystrokes required from an APRS device to key 
in....

Thank You,

Well, you still see them over here.  I guess the Cell 
  companies have trained us to lower expectations.

The first message I 
  sent (via email-2) did display all the junk (no message text), but then later 
  ones from the same service did the reboot thing.  That's why I'm thinking 
  the bit bucket needs to be emptied, or something similar.  I think I'll 
  let her clear it all out and try the original email service one last time, 
  unless there's a 3rd service out there to try, or some way to configure 
  (format) what it delivers.

But, yeah, even without the messages she 
  occasionally complains of it turning itself off every once in a while.  
  Voice quality is a challenge on any mobile phone, another thing we've been 
  "trained" on.

Me, well, I don't have a cell phone...  If I'm in 
  the office, leave a message and I'll get back to you.  If I'm in the car, 
  try the Auburn repeater :-).
