RE: kannel errno 11

[Rafael Luque Leiva]

I am using 'at2'. 

My last test consisted of patching smsc_at2.c with this smsc_at2.path

Both patched kannel-1.2.0 and last snapshot kannel send long messages,
however I only receive correctly the first characters of message and the
character '@' repeteadly until the end of sms.

Here is a smsbox log excerpt:
