سلام
تا حالا در مورد کار با پورتها و درگاه ها کسی موضوعی مطرح نکرده اگر هم شده کاملا به نتیجه نرسیده. من یکسری توابع و پروژه هایی رو در این باره جمع آوری کردم و اینجا می زارم شما هم همکاری کنید تا مجموعه کاملتر بشه.
توابع و پروژهای بدرد بخور برای کار با پورتها

شماره گیری با مودم
تبدیل کدهای دریافتی از پورت به کد اسکی و نمایش آن
یک برنامه کامل برای برقراری ارتباط با مودم
یک مجموعه کامل برای توابع tapi
یک برنامه جانبی جالب برای برقراری ارتباط با هر پورت دلخواه و نمایش ورودی های آن به مبناهای مختلف.

ATAttention - this precedes all commands except A/ and +++A/Execute previous command - does not require a <CR>ACauses the modem to go off hook. If a call is coming in, the modem will try to answer it. The precedure for answering a call is a short silence and then an answer tone. Sending a character to the modem during this procedure will abort the answer sequence. The amount of time the modem will wait for a carrier is programmable by modifying the S7 register.
