	Generally you are looking at two places to change the baud rate. The 
first is in the computer/serial card itself. Generally it is best to 
keep this one fairly high to start. Most modems have a buffer which will 
 compensate for a higher speed.

	Next is the modem itself. This is a little more tricky. You'd have to 
read your manual for the specifics. It is possible to raise your baud 
rate while on line, but not advised. When two modems connect they 
negociate between them as to the quality of the line and the speed of 
the two modems. They will choose the best option between them. If one 
modem (not yours) is limited to 2400 baud this is the value they will 
use. If you DO want to up your baud rate from YOUR anyhow, you will need 
to send an init string to the modem. You will need to send an escape 
sequence to send an offline command. Then you will need to send another 
command to resume the connection. If you had already set it for, say, 
56K anyhow then the problem is the connection and not your modem. All 
you can do is hope it gets better or hang up and try again hoping you'll 
get a better connection.
