6530 Programmer’s Guide
p1 is an ASCII character that specifies the number of times the
character determined by p2 is repeated. Bit 7 is a parity bit; bits 6 - 0
represent the number of times to repeat the character (offset by 20).
p2 is the displayable ASCII character to repeat. Bits 7-0 comprise
the ASCII character.
For example, the command
DC2 3F 41
repeats the uppercase letter A 31 times, beginning at the buffer address of
the selected page.
Status Information This group of escape sequences provides status information about the
6530, the Aux1 and Aux2 devices, and current workstation or PC
directory.
Read Terminal Status (Esc ^)
The Esc ^ sequence causes the 6530 to transmit its status and the status
of the Auxl or Aux2 device to the host. This returned status message has
the following general format:
S0H ? status term-id maj-rev-level max-page
fields1 fields2
terminator
where:
S0H is a control character (01H) that acts as a start of header for
messages returned to the host.
The question mark (?) identifies this message as a status message.
status is an ASCII character whose binary value indicates the
status of the Auxl and Aux2 devices as follows:
Bit 6543210
1 = self test passed (TS530 only)
1 = power up
1 = Aux1 timeout
1 = Aux1 busy
1 = Aux2 timeout
1 = Aux2 busy
