I would check with Scottrade. This is part of the email I got from them on June 13.
"You inquired about transferring symbol ENTI into Scottrade.
Unfortunately, symbol ENTI is not a symbol we would be able to accept as of the time of this writing.
We take stock that is eligible through DTC. DTC is the fastest, most cost effective way to send stock to the transfer agents. In addition, Scottrade will no longer accept transfers of OTC stocks priced below $1 (those not listed on a U.S. exchange such as the NYSE, AMEX or NASDAQ), unless the transfer includes other listed securities (stocks, options, bonds and mutual funds) or cash whose combined value exceeds the value of the OTC stocks priced under $1."
