IBM 4201 Proprinter connection
Cable pin assignment
If you have an IBM 4201 Proprinter with a serial interface, you can attach the
printer to the auxiliary port of the IBM 3164 via the I/O cable (part number
6343373).
In Print operation, the ASCII characters (refer to page 5-79) are transferred to
the printer while the special graphic characters and the alternate characters are
converted into space characters.
The Passthrough operation of the IBM 3164 enables you to use the IBM 4201
Proprinter with its full functions such as the use of the 4201 character fonts
and downloaded characters.
Note: In Trace operation, prints may not be formatted properly because of the
difference in the command formats of the IBM 3164 and the IBM 4201
Proprinter.
As a precaution against a printer buffer overrun, one of the following is
recommended:
1. Use of the XON/XOFF pacing function which is enabled by setting bit 1
in parameter 3 of the Set Control 6 command to on (1) (refer to page
5-20).
2. Use of the OTR pacing function which is enabled by setting bits 4
through 1 in parameter 3 of the Set Control 7 command to '0101' (refer to
page 5-22).
Shown below is the pin assignment for the I/O cable (part number 6343373).
