/**---------------------- #define of sizes of things ---------------------

        Frames can be at most 2.55 secs (sent) or 3.45 secs (recvd) long, or
        2.55 * 300/8 = 96 bytes and 132 bytes long respectively

        Dialstrings are limited to 512 bytes (arbitrarily)

        Commands (except dial) are never more than about 10-20 bytes long, so
        we use a buffer of 40 bytes. Replies are never big at all, but we
        might hold a frame in there, so keep it same size as a Framebuffer

        The Dial command is ATDT <string><CR>, so we use 512+10 bytes buffer
