Retro Challenge - 2014 WW - Day 8

Multiple Modem Support

Added multiple modem support into the dial up server. Set the modem initialization strings in the configuration file along with the com ports for each modem required.

Plugged in the Hayes and the USB modem below and configured them in the new settings file.

USB Modem

Tried to get the USB modem to work, it responds as expected but there is something wrong with the data being sent to the terminal. It looks like its not using 7 even one, not sure why this is the case.

You can see it is sending the screen as certain characters are displayed correctly, it seems to be messing up the rest.

Have played around with several of the modem settings and can't seem to get this to work correctly, the Hayes modem works perfectly with the same settings.

After some more investigation it seems that the USB modem is using the wrong parity setting, it appears to be using odd parity even when I've asked for even.
