What I'm seeing is that it returns Z set if break was pressed. Can
someone confirm this for me?

It's generally a good idea to search the mail archives for answers to
questions like yours.
(Lately I've been reading the list ONLY topically, rather than
chronologically, so I have 14,824 unread messages.)
The confirmation to your observation was posted by Ron Wiesen in the
message below.

Listed below is some errata to Radio Shack publication "Model 100 ROM
Functions (700-2245)".
page 2 ENDLCD End of LCD memory FF3F
(not FF40)
page 4 BRKCHK Check for BREAK characters only (CTRL-C or -S)
I believe the Z flag (not C flag) is the indicator.
Also, the description is simplistic in that it does not cover
the influnce of the cell at FFEB, which indicates the prior
state of suspension/release.
page 7 SENSCQ Send an XON resume character (CTL-Q)
Description is simplistic in that it does not cover the influence
of condition flags in memory, which can prevent transmission of
an XON.
page 7 SENDCS Send an XOFF pause character (CTL-S)
Description is simplistic in that it does not cover the influence
of condition flags in memory, which can prevent transmission of
an XOFF.
Page 7 SD232C Send a character to the RS-232 or Modem (with XON/XOFF)
Exit conditions:
C flag set is BREAK is pressed.
Page 7 SNDCOM Send a character to the RS-232 or Modem (without XON/XOFF flow
control)
Exit conditions:
C flag set is BREAK is pressed.
Page 9 SYNCW Write cassette header and sync byte only
Exit conditions:
C flag set is BREAK is pressed.
Page 9 SYNCR Read cassette header and sync byte only
Exit conditions:
C flag set is BREAK is pressed.
Page 9 DATAW Write a character to cassette (no checksum)
Exit conditions:
C flag set is BREAK is pressed.
Page 11 MASDEL Delete specified number of characters
Exit conditions:
HL is preserved
(BC not preserved)
Page 11 TIME Read system TIME
Exit conditions:
HL advanced by 8
Page 11 DATE Read system DATE
Exit conditions:
HL advanced by 8
Page 12 DAY Read system Day
Exit conditions:
HL advanced by 3
