It has the 243 firmware upgrade. The 243 revision prom to the USR Courier did improve its performance in the presence of phone line irregularities - you can now use it on dialup lines most of the time. It did NOT cure the problem that the Courier uses the Bell 2400 handshake instead of the v.22bis handshake. There are a few modems out there which simply do not accomodate the earlier Bell standard and will therefore refuse to connect to the Courier. (We have several Rixon modems that exhibit this refusal, and the early versions of the Anchor Lightning 2400 did too.) Luckily, most current 2400bps modems will accomodate both the Bell and V.22bis handshake, so you may never see the problem. Caveat Emptor. Test it out. See if you can get some sort of return privileges if it isn't what you can use. Sure is a nice price!
