Wippeerclose

Hello,

I’am currently develop an application based on a FASTRACK M1306B with Wipsoft 3.01. All AT command are sent through Hyperterminal.
I can dial, send SMS, but my problem is :
when I follow the example decribe in the WIP_AT_COMMANDS_USER_GUID_V3.01 in order to send an e-mail(8.6 SMTP), after +WIPCREATE (I specified smtp server, user name and password) the modem answer OK then +WIPREADY: 6,1. But few second later the modem answer again with +WIPPEERCLOSE: 6, 1.
It’s an unsollicited answer, but why?
Someone have already had the same problem, or someone could help me?
Thank you in advance, loic

PS : sorry for my english
