I'm hoping for some help with PC-Scheme serial I/O. I'm having no trouble with output, but I'm getting results I don't understand when I use an input-port defined with (define modem-in (open-input-file "com1")). For example, (read-line modem-in) will often give me an undocumented "[VM ERROR encountered!] 196". (char-ready? modem-in) will often go away for several minutes before returning #\. The hardware is fine. Any comments welcome via email. Adrian_Boyko@cc.sfu.ca b3076906@scheme.cs.ubc.ca
