1. USB hub... then USB to rs232...
2. rocketport - very expensive solution hehe
3. DIY approach - mux/demux ckt for serial port. (ideal for device that uses RX/TX only)

wala namang limit. minsan lang hindi na tama response ng program doon sa transmission dahil sa ibang program, Synchronous reception ang implementation ng UART. for the past few weeks, successful ang paggamit namin ng multiple CD-R King USB to RS232 (8 to 10 per PC) nakakabit sa PCI USB card. karamihan lang sa program, hanggang COM99 lang ang mare-recognize. OT: may pagka-"tanga" pala ang SerialPort class ng .NET. hindi niya nakikilala ang serial port na may ibang pangalan, kailangan nagsisimula sa COM. |
