For some application, I need to use a Wavecom FS20 as a dial up modem froma windows based PC.
I have done this without any problem on WinXP:
- define a standard modem 56000bps
- create a dial up connection
- launch the connection and it owrked
I did the same thing with Win7. I can talk to the modem when using AT command through Putty.
I can create the standard modem and the dial up connection but every time I try to lauch the connection I got the Error 633 : modem already in use or not properly configured.
I checkecd and double checked there is no other program using the modem.
I removed and recreated the modem and connection, no improvment.
Any idea welcome!
