Some ISA 'internal modems' don't have real 8250-family UARTs, they attempt to emulate them using their onboard processors. Most of these are quite slow at generating interrupts, and responding in general, so waiting a while gives them time to react. Over the last six months or so, we've had a number of successful results with these delays, hence bde committing them. > HOSOKAWA, Tatsumi E-mail: hosokawa@mt.cs.keio.ac.jp -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] Collector of old Unix hardware.
