status is an ASCII character whose binary value indicates the
status of the Auxl and Aux2 devices as follows:
Bit 0 is always set to 1 for compatibility with the 6530. Bit 1 is set
the first time this escape sequence is issued after a power up. Bits 2
and 4 are set or cleared based on the last output operation to the
respective devices. Bits 3 and 5 are set only when the respective
ports are busy outputting data.
term-id is an ASCII character that identifies the terminal type.
For the 6530, this is always F.
maj-rev-level is an ASCII character that identifies the major
revision level of the 6530 (for example, B for B30 or B40).
CR is a control character (0DH) that terminates the message.
Read Full Revision Level (Esc _)
The Esc _ sequence causes the 6530 to transmit its full revision level to
the host. The returned message has the following general format
SOH # rev-level T0 device-rev-level CR
where:
SOH is a control character (01H) that acts as a start of header for
messages returned to the host.
The number sign (#) identifies this message as a firmware message.
rev-level consists of three ASCII characters that identify the
6530’s revision level (for example, B42).
