با سلام
من ارسال پیامک به صورت فارسی را با استفاده از دستورات AT نیاز دارم
گفتنی است که در این سایت جستجو صورت گرفته و نتیجه برای حل این مساله نبوده است
لازم به ذکر است که از OCX , DLL معروف که در سایت ذکر شده نمی خواهم استفاده کنم
فقط وفقط دستورات AT
اتفاقا منم نیاز دارم
روش استفادش رو هم میگفتین خیلی خب بود
میشه یک پروژه بدی
من الان چند وقت هست دنبال میگردم که هم بتونم اس ام اس بزنم و هم بگیرم از طریق کامپیوتر
خواهشن کسی در مورد این سوال کمک کنه
سلام
باید با PDU emcoding , decoding آشنا بشی
یه کم درموردشون تو سایت های زبان اصلی و فارسی تحقیق کن
من هم دنبالش هستم ولی کار چنذلن راحتی نیست
اگه با قالب و انواع و روش های کدگذاری و گشایی pdu آشنا شی متوجه میشی
هیچی غیرممکن نیس اونم برای ایرانی
موافقی ابا هم اون ocx رو طراحی کنیم
یه سری به http://www.eaglevb.blogfa.com/ بزن
یه نمونه برنامه کوچیک همراه راهنمای کامل دستورات at هست گذاشتم شاید مفیدت باشه
ولی من هر چی بیشتر پی گیر این موضوع شدم دیدم ارزش نداره وقتمون رو برای GSM Modem هدر بدیم
چون سرعتش خیلی پایینه و محدودیتش بالا!
به نظر من این گزینه رو باید بی خیال شیم و بریم دنبال گزینه های بهتر مثل وب سرویس ها
راه حل pdu کردن پیفام sms
البته باید از دوست عزیزم دانیال تشکر کنم که در این زمینه کمکم کرد

با سلام
در مورد نحوه کار این کد نمیشه توضیح بدید؟؟آخه چیزی ازش نفهمیدم؟میشه بگید چطوری یک اس ام اس فارسی با فرمت پی دی یو ارسال میشه؟؟چطور باید تو برنامه توابع رو فراخوانی کرد(منظورم ترتیبشه)؟
