Can anybody recommend a USB adaptor that provides four serial ports and works well in Linux? I used to have one of these beasts driving four GSM modems, with kannel used to send and receive SMS. It's recently died, though, and finding a replacement is problematic.
I've been toying with a Quatech QSU2-100, which ships with source for a driver that claims to be compatible with kernels up to and including 2.6.18. Experiments with CentOS 5.0 show that I'm able to talk to an attached modem in minicom and issue AT commands just fine, but kannel reports an incorrect response when it tries to communicate with a modem. So it closes and re-opens the device, at which point the kernel promptly panics. So, does anybody have any positive experiences with multi-port USB adaptors? Or am I going to be adding four separate adaptors and a hub to my mess of cabling? -- Pete -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
