Not exactly, the original MAX3232 is capable of transferring up to 1Mbaud, the ST3232 400kbaud only. MIKE

According to the Maxim data sheet only the MAX3237 can do megabaud, and only when the MBAUD input is active. Otherwise it is 250kbps. The MAX3232 seems to specify the maximum data rate as MIN 120kbps TYP 235kbps, load of 3k ohms, 1000pF, one transmitter switching. -- glen______________________________
