Bulk sms sending using C# and GSMComm

1
Hi!
i found your article http://bytes.com/topic/c-sharp/insig...k-sms-sender-c matched my condition, and i'm also applying it on my system. However it works fine when i send bulk sms of 4 or 5, not when i send a bulk of 58 sms. the sms were sent in for loop and i did use system.threading.thread.sleep(10000). I'm not sure if it's too much, but with or without thread.sleep(), none of the messages was sent. Moreover, to make sure, i sent single sms (it worked), then bulk of sms of 5( also worked), and then send sms of 58 (it didn't work).
I dont know if it's because of modem, telecom provider or the GSMComm class.

Also, i'm hoping you have some ideas on how to receive delivery report or sms-sending status to know if there's error or failure.

Sounds like you're having a timeout issue, try changing

Expand|Select|Wrap|Line Numbers
  1. system.threading.thread.sleep(10000)
to
Expand|Select|Wrap|Line Numbers
  1. system.threading.thread.sleep(1000)
As he has in his example and see if that changes anything.
