Added a fix so if the fax/data modem uses MM.TSY and the phone/SMS
is some other modem also using MM.TSY, the phone/SMS modem will be
changed to the same value as the fax/data modem

Check if the fax/data modem uses MM.TSY
If not then thats ok so return and continue connection setup
Find out which modem is used for Phone/SMS services
If it is the same modem, again that's ok so return and continue setup
Check if the phone/sms modem uses MM.TSY
If not then thats ok so return and continue connection setup
So now we know fax/data and phone/sms use different modems but
both modems are driven by MM.TSY
To avoid a panic in MM.TSY, set the phone/sms modem to be the same as
the fax/data modem
