For IR, I believe FIR mode can get up to 4Mbps, but requires a kernel module
specific to your chipset. Lacking that, you'll get max standard serial port
connectivity (115200 bps ?). There's also murmuring of a new IRDA spec coming
out with even faster data rates (IRDA 2 ?). In any case, it won't be IR
limiting you to 9600 bps.
GSM is set at a fixed rate of 9600 bps per channel. Of course, you can
probably move a bit more data with compression, etc.
I'm not as familiar with CDMA or TDMA, but you ought to be able to do better
than 9600 bps over an IRDA connection with either of those (they might be
limited by other traffic on the cell tower, however).
