160 all Request invalid for line state:
•
Requested WRITE, 
WRITEREAD, or 
Control 14 (send RSET) 
operation when the line 
was disconnected or 
offline.
•
Requested WRITE or 
WRITEREAD would 
have caused more 
WRITE operations to be 
concurrently pending 
than maximum specified 
when the line was 
opened.
•
Requested CONTROL 
operation was issued 
when one was already 
pending (only one 
CONTROL operation 
can be pending at any 
time).
•
Incorrect parameter was 
used for CONTROL 
call.
Check your program and recode if 
necessary. For invalid state, either a 
logic error is in the code (for 
example, you issued WRITE request 
before establishing NRM), or your 
application is not handling a previous 
error code properly.
161 all  Impossible event occurred 
for line state.
Check code.
162 all  Operation timed out Retry; if retry does not work, contact 
the operator.
163 all RNR was received. If RNR RETRY is enabled, message 
is retried for retry number of times 
before error is issued. If RNR 
RETRY is not enabled, error is 
issued upon initial receipt of RNR.
164 ABM DISC received or 
CONTROL 18 (send DISC) 
call issued while request is 
outstanding.
Should not be treated as an error 
condition.
164 all FRMR received. Perform higher-level recovery; 
specific action is device-dependent.
164 NRM RD, DM, or FRMR received. Send the appropriate mode-set 
command. 
169 NRM Station not ready or disabled. Perform higher-level recovery.
