How to set/unset RTS ?

[Rupert G. Goldie]

I'm posting this for a friend who currently doesn't have Net access. 

She is using: C-Unix Sco Sys V and a Sendata modem using V23 (1200/75)
She wants to be able to set/unset RTS. How can she do it ? I suggested using
termio ioctls but she couldn't find anything relevant there.
Any help would be appreciated.
