Hi :idea: ,
I am looking for some input on “Dialup Connectivity” in .Net
My scenario being I will have a config file containing the parameters
required for modem connection like the phone number, data bit, baud
rate, etc. Here I have instantiate the connection and send a string
to the server (machine I connect to) and where I will receive a
message once the string has been received.
Any code and documentation on how to set this project scenario will be
welcome.
Thanking you in advance.
