MS Comm question

Hi there,

I'm using the MS Comm control to receive data from the modem. (well it will eventually be able to :))

I'm just curious how this all works.

1) First of all, when you receive data, does the sending application wait for the receiving application to receive the data? or does it just spit it out continuously?

2) Also once a call has been detected and the initialization code is received (which signals a new message is coming in), I need to reply with another special code. How do you send data using the MS Comm? I'm sure its simple, just never done it before.

That's all for now...

Thanx for any help
