using two dialup modems with a single macintosh?

[chelseayr]

normally would had tried it for myself to answer this already but as it'll probably take a while to finally find the logic board I wanted I decided it couldn't hurt to ask someone else [here]

 

not sure if the control panel might be confused by it or not but would there maybe be issue with having two active modem (script files are different enough) in the guise of the internal one handling receiving voice/fax requests as they come, and using an external v.92-capable modem to block up the line from time to time aka being on the internet?

 

thanks for not minding this unusual peripheral topic
