From CoCopedia

At one point in time CoCoPro! obtained a number of Tandy DC Modem Paks, which were basically useless with their 300 Baud Modem. Fortunately, there was a hack devised (published in Raibow I believe) to turn the Modem Pack into the equivalent of the Tandy RS232 Pak. The CoCoPro! RS232 Paks are old DC Modem Paks repurposed.
