Abstract: With TELCOM, your PDP-8 or PDP-12 can perform computer

to computer or computer to remote terminal or other device commu-

nications. Communication codes must be 7- or 8-bit ASCII and may be

odd, even, or mark parity.Default program status has the PDP emulating a

remote demand terminal. The user may exit TELCOM at any time while in

this status, perform other PDP processing, then resume TELCOM

operation at the point of exit. Additional features provide for data

transfers through the interface to and from file-oriented devices. File

characters are packed and unpacked according to OS/8 (OS/12)

conventions. Files created by TELCOM are readable by other operating

system programs (such as PIP, EDIT, BASIC, etc.). TELCOM utilizes an

asynchronous modem interface for telecommunications at speeds up to

1200 baud.

Restrictions: This program has not been tested beyond 1200 baud.
