AMTOR is an immediate command that switches Radio Port 1 of your PK-900 into
the AMTOR mode. Your PK-900 is automatically placed in ARQ Standby condition.
Your station is then available for automatic access by and response to any AMTOR
station that sends your SELCALL. The PK-900 can communicate using either the
CCIR 476 (4-character SELCALL) or the CCIR 625 (7-character SELCALL) protocol.
Your monitor will also display any inbound FEC (Mode B) transmissions.
See the MYSELCAL and MYIDENT commands to enter your 4 and 7 character SELCALLs.
