For those in BTL detailed information on the 212A modem can be obtained
in the DL's (Deveolment Letters), EL's (Engineering Letters), and of
course BSP's. All of these should be available at your local Engineering
Records office (or is it ITDS now?). For example, the first DL for the
212A is DL Data Systems no. 272 and its supplements.
