Not really as each IRQ will fetch 8 bits instead of 1. And I'm not sure that 
the bytes aren't buffered in the modem and then send with X number of bytes 
per IRQ. I'm pretty sure that the port will except more than 1 byte per IRQ.
I think one of the ZyXEL modems have a printer port connection but I haven't 
looked into it.
