Re: [Expectperl-discuss] Solaris horizontal linewrap problem

[Roland G. <Ro...@Gi...>]

Hmm, well I can confirm from my experience that solaris ptys are 
somewhat broken in many regards. But this doesn't help you. :-)

What comes to mind is to circumvent ptys completely. Have you considered 
using Net::Telnet instead of spawning a telnet program?

Hope this helps,

Roland
