Operating System: RSX-11M V3.2  Source Language: FORTRAN IV-PLUS
Memory Required: 18KW  Hardware Required: Serial Line Connection
Between PDP-11s.  Keywords: Data Communications
 
Abstract: XFR/XSL is a "master/slave" communications package
for "virtual terminal" and file transfer
capabilities between PDP-11s running RSX-11M. It runs
through a serial line (direct or through modems) between
the two PDP-11s, and allows a user at one machine to
"talk through" that machine to the other, and to
transfer ASCII files in either direction. It is designed
to run at 300 or 1200 baud, but could be modified to
transfer files at 9600 baud or to run on other operating
systems. The programs are well documented, written in
FORTRAN using QIO calls, and the file transfer protocol
includes good error-checking and recovery mechanisms.
 
Notes: QIO calls would need to be modified to run on most other
operating systems.
 
Restrictions: Virtual terminal mode maximum speed is 1200 baud.
