Figure 31. SSC Transmit/Receive Example (After Teleprocessing Completed)
If the mode is T, P, R, B, BT, or DT, the disk is positioned
at the original position before transmission or reception
took place, and the modem is conditioned to automatically
answer a telephone call if it is in an auto answer mode. If
the mode is TT, TI, PT, PI, RC , RJ, BI, BJ, BC, 01, OJ, or
DC, the modem is not conditioned to answer a telephone
call.
BSCA Error Conditions and Indications
Characters in parentheses indicate what is displayed in the
error indicator position of the display's status line.
Transparency Check (T)
This error condition occurs when the 3741 is in a transmit
(T) or a transmit/receive (B) mode, and one of the follow-
ing characters is read from disk: SYN, EDT, OLE, NAK,
ENO, ETB, ETX, ITB, STX, or SOH. The 3741 sends
ENO in place of the data link control character, and then
follows the response with an EDT.
