We are offering the GCG 8.0 release on our Digital AXP (Alpha) system
running OSF/1 and are experiencing some difficulties with the Seqed/lineup
software run over a Mac Telnet version 2.5 terminal. The problem is
relates to the arrow keys which the mapping for which is changed from ^[[A
^[[B ^[[C and ^[[D to ^[OA ^[OB ^[OC and ^[OD. This is not interpreted
correctly, and causes the editor to discard the escape O and print a
capital A B C or D to the screen. As seqed is fairly essential to the
running of a reasonable service, and most users connect through telnet 2.5
we are very concerned. I voiced these concerns to GCG and had the
following response:

Although I appreciate that it is difficult to cater for differences in
other peoples software, upgrading telnet accross arround 400 macs is not a
short term solution. The alternative suggested modification to the
config.tel file has the effect of turning off the arrow keys completely.
Has anyone else been able to resolve this issue, could they share it with
us. If not, can anyone suggest an alternative sequence editor in the
public domain, compatible with our system.
