v.what?

v.what? — A typo bit us in last week’s issue. The article on the PSI PowerModem incorrectly said that the modem uses v.32 error correction and v.32bis compression – those numbers should be v.42 error correction and v.42bis compression. Sorry for the confusion – the modem supports the v.32 and v.32bis communication protocols, which define the connection speed (9,600 bps or 14,400 bps), but are different from the error correction and compression protocols.
